Using a variable length array, write a C program that asks the user to enter test scores.Then, the program should calculate the average, determine the lowest test score, determine the letter grade, and display all three.
Answers
Answer:
Here is the C program :
#include<stdio.h> // to use input output functions
int main(){ //start of main() function body
int n; //to store the number of tests taken
int test_scores[n], i; //a variable length array test_score
float sum=0,average; //to store the sum and average of test scores
int lowest; //to store the lowest test score
printf("Enter the number of tests taken :");//prompts user to enter number of test scores
scanf("%d",&n); / / reads the value of n from user
printf("Enter test scores: "); //prompts user to enter test scores
for(i=0; i<n; i++) {
scanf("%d",&test_scores[i]); //read the values of input test scores
sum = sum + test_scores[i]; } //calculates the sum of the test scores by adding the values of test scores
average=sum/n; // compute the average by dividing sum of all test scores with the total number of test scores
printf("Average is %.2f",average); //displays the average
printf("\nGrade is "); // prints Grade is
if (average >= 90) { //if value of average is greater than or equal to 90
printf("A"); } //print the grade letter A
else if(average >= 80 && average < 90) { //if value of average is greater than or equal to 80 and less than 90
printf("B"); } //print the grade letter B
else if(average>60 && average<80){ //if value of average is between 60 and 80
printf("C"); } //print the grade letter C
else if(average>40 && average<=60) { //if value of average is greater than 40 and less than or equals to 60
printf("D"); } //print the grade letter D
else { //if the value of average is below 40
printf("F"); } //print the grade letter F
lowest = test_scores[0]; //lowest points to the 1st element of test scores means the first input test score
for (int j = 1; j < n;j++) { //loop iterates through the scores
if (test_scores[j] < lowest) { // if the element at j-th index position of test_scores array is less than the element stored in the lowest variable
lowest = test_scores[j]; } } //then assign that element value of test_score to the lowest
printf("\nLowest test score is: %d.\n", lowest); } //displays the lowest test score
Explanation:
The program is well explained in the comments mentioned with each statement of the code.
The program prompts the user to enter the number of test scores as they are not already specified in the array because array test_scores is a variable length array which means its length is not fixed. The program then prompts the user to enter the test scores. The program then adds all the test scores and store the result in sum variable. Then it computes the average by dividing the value in sum variable to the number of test scores n. Then in order to determine the letter Grade the average value is used. The if else conditions are used to specify conditions in order to determine the Grade. Next the lowest score is determined by setting the value of lowest variable to the first element of the test_scores array. Then using for loop, the index variable j moves to each array element i.e. score and determines if the the value of element is less than that stored in the lowest variable. If the value positioned at j-th index of test_scores is less than that of lowest than this value is assigned to lowest. At last the lowest holds the minimum of the test scores.

Chain of custody is applied when examining digital evidence and checking for proof that no alterations have been made to the document. It ensures that the original piece of digital evidence which could be in text, image, video, or other electronic formats, is preserved and protected from alterations. Hashing algorithms which are mathematical computations that help to condense files are applied during this procedure.
Common hashing algorithms applied, include; the message digest 4, secure hashing algorithms 1, 2, 256, 224, 512, etc. The message digest 4 is used to evaluate why a particular piece of evidence was handled by an individual. This is further authenticated by examining the fingerprint.
A cashier distributes change using the maximum number of five-dollar bills, followed by one-dollar bills. Write a single statement that assigns num_ones with the number of distributed one-dollar bills given amount_to_change. Hint: Use %. Sample output with input: 19 Change for $ 19 3 five dollar bill(s) and 4 one dollar bill(s)
Answers
Answer:
num_ones = amount_to_change % 5
Explanation:
It is given that the cashier has to change the money in the maximum number of 5 dollar bills and remaining as $1 bills.
We have to write a single statement of code to assign the value to variable num_ones to find the value of $1 bills given amount_to_change.
Let us solve this by taking example:
If amount_to_change = $19
Then total number of $5 bills that can be given is 3. And amount that can be given as $5 bills is [tex]\bold{3 \times 5 = \$15}[/tex]
So, the remaining amount i.e. $19 - $15 = $4 will be given as one dollar bills.
Out of these $19, 4 bills of $1 can be found using the Modulus (%) operator.
Modulus operator leaves the remainder i.e.
Output of p % q is the remainder when a number 'p' is divided by 'q'.
19 % 5 = 4
4 is the number of one dollar bills to be given.
So, single line of code for the number of one dollar bills can be written as:
num_ones = amount_to_change % 5
Let us try it for amount_to_change = $30
We know that 6 number of $5 bills can be used to change the amount of $30 and no one dollar bill required.
num_ones = 30 % 5 = 0 (because 30 is completely divisible by 5 so remainder is 0)
So, the correct statement is:
num_ones = amount_to_change % 5

for x in range(len(names)): # loop through the names
dict[names[x]]=numbers[x] #maps each name to its phone number

numbers = ['404-555-1234', '678-555-5678', '770-555-9012']
print(phonebook(names, numbers))
Explanation:
The program has a function phonebook() that takes two parameters, name which is a list of names and numbers that is a list of phone numbers.
It then creates a dictionary. An empty dictionary is created using curly brackets. A dictionary A dictionary is used here to maps a names (keys) phone numbers (values) in order to create an unordered list of names and corresponding numbers.
for x in range(len(names)):
The above statement has a for loop and two methods i.e. range() and len()
len method is used to return the length of the names and range method returns sequence of numbers just to iterate as an index and this loops keeps iterating until x exceeds the length of names.
dict[names[x]]=numbers[x]
The above statement maps each name to its phone number by mapping the first name with the first umber, the second name with the second number and so on. This mapping is done using x which acts like an index here to map first name to first number and so on. For example dict[names[1]]=numbers[1] will map the name (element) at 1st index of the list to the number (element) at 1st index.
return dict retursn the dictionary and the format of dictionary is key:value where key is the name and value is the corresponding number.

print(compare_strings("They found some body.", "They found somebody.")) # False
Answers
Answer:
There is a problem in the given code in the following statement:
Problem:
punctuation = r"[.?!,;:-']"
This produces the following error:
Error:
bad character range
Fix:
The hyphen - should be placed at the start or end of punctuation characters. Here the role of hyphen is to determine the range of characters. Another way is to escape the hyphen - using using backslash \ symbol.
So the above statement becomes:
punctuation = r"[-.?!,;:']"
You can also do this:
punctuation = r"[.?!,;:'-]"
You can also change this statement as:
punctuation = r"[.?!,;:\-']"
Explanation:
The complete program is as follows. I have added a print statement print('string1:',string1,'\nstring2:',string2) that prints the string1 and string2 followed by return string1 == string2 which either returns true or false. However you can omit this print('string1:',string1,'\nstring2:',string2) statement and the output will just display either true or false
import re #to use regular expressions
def compare_strings(string1, string2): #function compare_strings that takes two strings as argument and compares them
string1 = string1.lower().strip() # converts the string1 characters to lowercase using lower() method and removes trailing blanks
string2 = string2.lower().strip() # converts the string1 characters to lowercase using lower() method and removes trailing blanks
punctuation = r"[-.?!,;:']" #regular expression for punctuation characters
string1 = re.sub(punctuation, r"", string1) # specifies RE pattern i.e. punctuation in the 1st argument, new string r in 2nd argument, and a string to be handle i.e. string1 in the 3rd argument
string2 = re.sub(punctuation, r"", string2) # same as above statement but works on string2 as 3rd argument
print('string1:',string1,'\nstring2:',string2) #prints both the strings separated with a new line
return string1 == string2 # compares strings and returns true if they matched else false

How many times does the following loop execute? double d; Random generator = new Random(); double x = generator.nextDouble() * 100; do { d = Math.sqrt(x) * Math.sqrt(x) - x; System.out.println(d); x = generator.nextDouble() * 10001; } while (d != 0); exactly once exactly twice can't be determined always infinite loop
Answers
Answer:
The number of execution can't always be determines
Explanation:
The following points should be noted
Variable d relies on variable x (both of double data type) for its value
d is calculated as
[tex]d = \sqrt{x}^2 - x[/tex]
Mere looking at the above expression, the value of d should be 0;
However, it doesn't work that way.
The variable x can assume two categories of values
Small Floating Point ValuesLarge Floating Point ValuesThe range of the above values depend on the system running the application;
When variable x assumes a small value,
[tex]d = \sqrt{x}^2 - x[/tex] will definitely result in 0 and the loop will terminate immediately because [tex]\sqrt{x}^2 = x[/tex]
When variable x assumes a large value,
[tex]d = \sqrt{x}^2 - x[/tex] will not result in 0 because their will be [tex]\sqrt{x}^2 \neq x[/tex]
The reason for this that, the compiler will approximate the value of [tex]\sqrt{x}^2[/tex] and this approximation will not be equal to [tex]x[/tex]
Hence, the loop will be executed again.
Since, the range of values variable x can assume can not be predetermined, then we can conclude that the number of times the loop will be executed can't be determined.

Explanation:
The first line imports the string module into the program
import string
The functipn easyCrypto() starts here
def easyCrypto(inputstring):
This line iterates through each character in the input string
for i in range(len(inputstring)):
The try except handles the error in the program
try:
This line gets the index of the current character (lower case)
ind = string.ascii_lowercase.index(inputstring[i])
This line adds 1 to the index
pos = ind+1
This line checks if the character is at even position
if pos%2 == 0:
If yes, it returns the alphabet before it
print(string.ascii_lowercase[ind-1],end="")
else:
It returns the alphabet after it, if otherwise
print(string.ascii_lowercase[ind+1],end="")
The except block does the same thing as the try block, but it handles uppercase letters
except:
ind = string.ascii_uppercase.index(inputstring[i])
pos = ind+1
if pos%2 == 0:
print(string.ascii_uppercase[ind-1],end="")
else:
print(string.ascii_uppercase[ind+1],end="")
The main starts here
This line prompts user for input
anystring = input("Enter a string: ")
This line calls the easyCrypto() function

Discuss the differences between dimensionality reduction based on aggregation and dimensionality reduction based on techniques such as PCA and SVD.
Answers
Answer:
Following are the difference to this question can be defined as follows:
Explanation:
In terms of projections of information into a reduced dimension group, we can consider the dimension structure of PCA and SVD technologies. In cases of a change in the length, based on consolidation, there's also a unit with dimensions. When we consider that the days have been aggregated by days or the trade of a commodity can be aggregated to both the area of the dimension, accumulation can be seen with a variance of dimension.Dimensionality reduction based on aggregation involves selection of important character and variable from a large variable and dimensionality reduction based on techniques with the use of PCA and SVD.
What is dimensionality?Dimensionality involves reducing features that have been written or identified or constructing less features from a pool of important features.
Principal components analysis(PCA) and Single value decomposition(SVD) is a form or analysis that can be used to reduce some character that are not important to an information and can also help to select important variables from among many variables.
Therefore, dimensionality reduction based on aggregation involves selection of important character and variable from a large variable and dimensionality reduction based on techniques with PCA and SVD.

This program prompts the user to enter starting salary, percentage increase in salary per year and number of years.
The for loop has range function which is used to specify how many times the salaries are going to be calculated for the number of years entered. It starts from 1 and ends after Years+1 means one value more than the year to display 10 too when user inputs 10 days.
The year and corresponding salary is displayed in output. At every iteration the starting salary is multiplied by annual percentage increase input by user. Here count is used to count the number of salaries per year, count-1 means it will start from 30000.

Use the get_seconds function to work out the amount of seconds in 2 hours and 30 minutes, then add this number to the amount of seconds in 45 minutes and 15 seconds. Then print the result.
Answers
Answer:
Since the get_seconds function is not given, I'll implement it myself;
The full program (get_seconds and main) written in python is as follows:
def get_seconds(hour,minute,seconds):
seconds = hour * 3600 + minute * 60 + seconds
return seconds
time1 = get_seconds(2,30,0)
time2 = get_seconds(0,45,15)
result = time1 + time2
print(result)
Explanation:
The get_seconds defines hour, minute and seconds as its arguments
This line defines the get_seconds function
def get_seconds(hour,minute,seconds):
This line calculates the second equivalent of the time passed to the function
seconds = hour * 3600 + minute * 60 + seconds
This line returns the the calculated seconds equivalent of time
return seconds
The main starts here
This line calculates the number of seconds in 2 hours and 30 minutes
time1 = get_seconds(2,30,0)
This line calculates the number of seconds in 45 minutes and 15 seconds
time2 = get_seconds(0,45,15)
This line adds both together
result = time1 + time2
This line prints the result
print(result)

An app developer is shopping for a cloud service that will allow him to build code, store information in a database and serve his application from a single place. What type of cloud service is he looking for?
Answers
Answer:
Platform as a Service (PaaS).
Explanation:
In this scenario, an app developer is shopping for a cloud service that will allow him to build code, store information in a database and serve his application from a single place. The type of cloud service he is looking for is a platform as a service (PaaS).
In Computer science, Platform as a Service (PaaS) refers to a type of cloud computing model in which a service provider makes available a platform that allow users (software developers) to build code (develop), run, store information in a database and manage applications over the internet.
The main purpose of a Platform as a Service (PaaS) is to provide an enabling environment for software developers to code without having to build and maintain complex infrastructure needed for the development, storage and launching of their software applications.
Simply stated, PaaS makes provision for all of the software and hardware tools required for all the stages associated with application development over the internet (web browser).
Hence, the advantage of the Platform as a Service (PaaS) is that, it avails software developers with enough convenience as well as simplicity, service availability, ease of licensing and reduced costs for the development of software applications.
These are the different types of Platform as a Service;
1. Private PaaS.
2. Public PaaS.
3. Hybrid PaaS.
4. Mobile PaaS.
5. Communications PaaS.
6. Open PaaS.
The software developers can choose any of the aforementioned types of PaaS that is suitable, effective and efficient for their applications development. Some examples of PaaS providers are Google, Microsoft, IBM, Oracle etc.
Write Album's PrintSongsShorterThan() to print all the songs from the album shorter than the value of the parameter songDuration. Use Song's PrintSong() to print the songs.

musicAlbum.SetName(albumName);
musicAlbum.InputSongs();
musicAlbum.PrintName();
musicAlbum.PrintSongsShorterThan(210);
return 0;
}
Answers
Answer:
Here is the function PrintSongsShorterThan() which prints all the songs from the album shorter than the value of the parameter songDuration.
void Album::PrintSongsShorterThan(int songDuration) const {
unsigned int i;
Song currSong;
cout << "Songs shorter than " << songDuration << " seconds:" << endl;
for(int i=0; i<albumSongs.size(); i++){
currSong = albumSongs.at(i);
if(currSong.GetDuration()<songDuration){
currSong.PrintSong(); } } }
Explanation:
I will explain the working of the for loop in the above function.
The loop has a variable i that is initialized to 0. The loop continues to execute until the value of i exceeds the albumSongs vector size. The albumSongs is a Song type vector and vector works just like a dynamic array to store sequences.
At each iteration the for loop checks if the value of i is less than the size of albumSongs. If it is true then the statement inside the loop body execute. The at() is a vector function that is used to return a reference to the element at i-th position in the albumSongs. So the album song at the i-th index of albumSongs is assigned to the currSong. This currSong works as an instance. Next the if condition checks if that album song's duration is less than the specified value of songDuration. Here the method GetDuration() is used to return the value of duration of the song. If this condition evaluates to true then the printSong method is called using currSong object. The printSong() method has a statement cout << name << " - " << duration << endl; which prints/displays the name of the song with its duration.
If you see the main() function statement: musicAlbum.PrintSongsShorterThan(210);
The musicAlbum is the Album object to access the PrintSongsShorterThan(210) The value passed to this method is 210 which means this is the value of the songDuration.
As we know that the parameter of PrintSongsShorterThan method is songDuration. So the duration of each song in albumSongs vector is checked by this function and if the song duration is less than 210 then the name of the song along with its duration is displayed on the output screen.
For example if the album name is Anonymous and the songs name along with their duration are:
ABC 400
XYZ 123
CDE 300
GHI 200
KLM 100
Then the above program displays the following output when the user types "quit" after entering the above information.
Anonymous
Songs shorter than 210 seconds:
XYZ - 123
GHI - 200
KLM - 100
Notice that the song name ABC and CDE are not displayed because they exceed the songDuration i.e. 210.
The output is attached.
The code below takes the list of country, country, and searches to see if it is in the dictionary gold which shows some countries who won gold during the Olympics. However, this code currently does not work. Correctly add try/except clause in the code so that it will correctly populate the list, country_gold, with either the number of golds won or the string "Did not get gold".

2 gold = {"US":46, "Fiji":1, "Great Britain":27, "Cuba":5, "Thailand":2, "China":26, "France":10}
3 country = ["Fiji", "Chile", "Mexico", "France", "Norway", "US"]
4 country_gold = []

6 for x in country:
7 country_gold.append(gold[x])
8 country_gold.append("Did not get gold")
Answers
Answer:
Modify your program by replacing
for x in country:
country_gold.append(gold[x])
country_gold.append("Did not get gold")
with
for x in country:
try:
country_gold.append(gold[x])
except:
country_gold.append("Did not get gold")
Explanation:
The addition of try/except clause in the program is to let the program manage error;
In this case, the program checks for a country in the list country; This is implemented using the following line
for x in country:
If the country exists, the statement in the try block is executed
try:
country_gold.append(gold[x]) ->This appends the country name to the country_gold list
Otherwise, the statement in the except clause is executed
except:
country_gold.append("Did not get gold") -> This appends "Did not get gold" to the country_gold list
To confirm what you've done, you may add the following line of code at the end of the program: print(country_gold)

Answers
Answer:
1. Blockchain Technology: Blockchain is a distributed ledger technology that lets data to be stored globally on its servers and it is based on a P2P topology which makes it difficult for someone to tamper with the network.
It can be used as a cryptocurrency wallet that supports BitCoin, Ethereum, etc.
An advantage of it is that it is distributed among several users and stable.
A disadvantage for a developing country like Ghana is that once a blockchain is sent, it cannot go back which brings up the question of security.
2.Artificial Intelligence: This technology is simply the simulation of human intelligence in machines. AI can be used for problem-solving and learning. An advantage of AI is that it reduces human error and is fast in solving problems. A disadvantage of AI is that its expensive to maintain and also it does not improve with experience.
3. Global Positioning System: GPS is a satellite-based positioning system that is used to pinpoint and track location. It has the advantage of being available worldwide and information is provided to users in real-time. One disadvantage of the GPS for a developing country like Ghana is that electromagnetic interference can affect the accuracy of the GPS.
4. 5G Network: This is the 5th generation of mobile internet connectivity that gives super fast download and upload speeds when compared to its predecessors 4G, 3G, 2G, and Edge networks.
One major disadvantage of 5G for a developing country like Ghana is that it is expensive and quite unknown and its security and privacy issues are yet to be resolved.
