Explanation:
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.
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)
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.

using namespace std;
class Song {
public:
void SetNameAndDuration(string songName, int songDuration) {
name = songName;
duration = songDuration;
}
void PrintSong() const {
cout << name << " - " << duration << endl;
}
string GetName() const { return name; }
int GetDuration() const { return duration; }

vector albumSongs;
};
void Album::InputSongs() {
Song currSong;
string currName;
int currDuration;
cin >> currName;
while (currName != "quit") {
cin >> currDuration;
currSong.SetNameAndDuration(currName, currDuration);
albumSongs.push_back(currSong);
cin >> currName;
}
}
void Album::PrintSongsShorterThan(int songDuration) const {
unsigned int i;

cout << "Songs shorter than " << songDuration << " seconds:" << endl;
/* Your code goes here */
}
int main() {
Album musicAlbum;
string albumName;
getline(cin, albumName);
musicAlbum.SetName(albumName);
musicAlbum.InputSongs();
musicAlbum.PrintName();
musicAlbum.PrintSongsShorterThan(210);
return 0;
}
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.
3.16 (Gas Mileage) Drivers are concerned with the mileage obtained by their automobiles. One driver has kept track of several tankfuls of gasoline by recording miles driven and gallons used for each tankful. Develop a program that will input the miles driven and gallons used for each tankful. The program should calculate and display the miles per gallon obtained for each tankful. After processing all input information, the program should calculate and print the combined miles per gallon obtained for all tankfuls. Here is a sample input/output dialog:
Answer:
I am writing a C program.
#include <stdio.h> // for using input output functions
#include <stdbool.h> // for using a bool value as data type
int main() { // start of the main() function body
int count=0; //count the number of entries
double gallons, miles, MilesperGallon, combined_avg, sum; //declare variables
while(true) {// takes input gallons and miles value from user and computes avg miles per gallon
printf( "Enter the gallons used (-1 to stop): \n" ); //prompts user to enter value of gallons or enter -1 to stop
scanf( "%lf", &gallons );//reads the value of gallons from user
if ( gallons == -1 ) {// if user enters -1
combined_avg = sum / count; //displays the combined average by dividing total of miles per drives to no of entries
printf( "Combined miles per gallon for all tankfuls: %lf\n", combined_avg ); //displays overall average value
break;} //ends the loop
printf( "Enter the miles driven: \n" ); //if user does not enter -1 then prompts the user to enter value of miles
scanf( "%lf", &miles ); //read the value of miles from user
MilesperGallon = miles / gallons; //compute the miles per gallon
printf( "The miles per gallon for tankful: %lf\n", MilesperGallon ); //display the computed value of miles per gallon
sum += MilesperGallon; //adds all the computed miles per gallons values
count += 1; } } //counts number of tankfuls (input entries)
Explanation:
The program takes as input the miles driven and gallons used for each tankful. These values are stored in miles and gallons variables. The program calculates and displays the miles per gallon MilesperGallon obtained for each tankful by dividing the miles driven with the gallons used. The while loop continues to execute until the user enters -1. After user enters -1, the program calculates and prints the combined miles per gallon obtained for all tankful. At the computation of MilesperGallon for each tankful, the value of MilesperGallon are added and stored in sum variable. The count variable works as a counter which is incremented to 1 after each entry. For example if user enters values for miles and gallons and the program displays MilesperGallon then at the end of this iteration the value of count is incremented to 1. This value of incremented for each tankful and then these values are added. The program's output is attached.

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
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.
QUESTION 6 Which of the following is a class A IPv4 address? a. 118.20.210.254 b. 183.16.17.30 c. 215.16.17.30 d. 255.255.0.0
Answer:
a. 118.20.210.254
Explanation:
Here are the few characteristics of Class A:
First bit of the first octet of class A is 0.
This class has 8 bits for network and 24 bits for hosts.
The default sub-net mask for class A IP address is 255.0.0.0
Lets see if the first bit of first octet of 118.20.210.254 address is 0.
118 in binary (8 bits) can be represented as : 1110110
To complete 8 bits add a 0 to the left.
01110110
First bit of the first octet of class A is 0 So this is class A address.
For option b the first octet is : 183 in the form of bits = 10110111 So it is not class A address
For option c the first octet is 215 in the form of bits = 11010111 So it is not class A address
For option d the first octet is 255 in the form of bits = 11111111. The first bit of first octet is not 0 so it is also not class A address.

Code Example 4-1
var name = prompt("Enter the name to print on your tee-shirt");
while (name.length > 12) {
name = prompt("Too long. Enter a name with fewer than 12 characters.");
}
alert("The name to be printed is " + name.toUpperCase());
What will happen if the user enters Willy Shakespeare at the first prompt?
A. The user will be prompted to enter a different name.
B. The alert will display The name to be printed is " + name.toUpperCase().
C. The alert will display The name to be printed is WILLY SHAKESPEARE.
D. The alert will display The name to be printed is WILLY SHAKES.
Answer:
(a) The user will be prompted to enter a different name
Explanation:
Given code;
--------------------------------------------------------------------------------------------------------
var name = prompt("Enter the name to print on your tee-shirt");
while (name.length > 12) {
name = prompt("Too long. Enter a name with fewer than 12 characters.");
}
alert("The name to be printed is " + name.toUpperCase());
--------------------------------------------------------------------------------------------------------
=>The first line of the code prompts the user to enter some name to be printed on their tee-shirt, and the input from the user is saved in a variable called name.
=> In the while block, the name variable is checked. If the length of the value of the variable is greater than 12 then a new prompt that says "Too long. Enter a name with fewer than 12 characters" is displayed.
=> In the last line, if the name variable is checked and the length is less than 12, then an alert statement showing the name in uppercase is displayed with some prepended texts.
Now, if the user enters Willy Shakespeare at the first prompt, the while block will be executed since Willy Shakespeare has over 12 characters.
In other words, the prompt in the while block, asking the user to enter a different name will be displayed. i.e
"Too long. Enter a name with fewer than 12 characters"

Write a method named removeDuplicates that accepts a string parameter and returns a new string with all consecutive occurrences of the same character in the string replaced by a single occurrence of that character. For example, the call of removeDuplicates("bookkeeeeeper") should return "bokeper" .
Answer:
//Method definition
//Method receives a String argument and returns a String value
public static String removeDuplicates(String str){
//Create a new string to hold the unique characters
String newString = "";
//Create a loop to cycle through each of the characters in the
//original string.
for(int i=0; i<str.length(); i++){
// For each of the cycles, using the indexOf() method,
// check if the character at that position
// already exists in the new string.
if(newString.indexOf(str.charAt(i)) == -1){
//if it does not exist, add it to the new string
newString += str.charAt(i);
} //End of if statement
} //End of for statement
return newString; // return the new string
} //End of method definition
Sample Output:
removeDuplicates("bookkeeeeeper") => "bokeper"

In the Stop-and-Wait flow-control protocol, what best describes the sender’s (S) and receiver’s (R) respective window sizes?
Answer:
The answer is "For the stop and wait the value of S and R is equal to 1".
Explanation:
As we know that, the SR protocol is also known as the automatic repeat request (ARQ), this process allows the sender to sends a series of frames with window size, without waiting for the particular ACK of the recipient including with Go-Back-N ARQ. This process is mainly used in the data link layer, which uses the sliding window method for the reliable provisioning of data frames, that's why for the SR protocol the value of S =R and S> 1.Steve wants to take charge of his finances.

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)
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
