Answer:
The scripts are:
1. SELECT * FROM planes
2. UPDATE planes SET YEAR = 2013 WHERE year IS NULL
3. INSERT INTO planes (Tailnum, Year, type, Manufacturer, Model, Engines, Seats) VALUES ('N15501',2013,'Fixed wing single engine', 'BOEING', 'A222-101',3,100,NULL)
4. DELETE FROM planes WHERE Tailnum = 'N15501'
Explanation:
1. SELECT * FROM planes
To select all from a table, use select * from [table-name]. In this case, the table name is planes
2. UPDATE [tex]planes\ SET[/tex] YEAR = 2013 WHERE year IS NULL
To do this, we use the update query which is as follows:
UPDATE [table-name] SET [column-name]= [value] WHERE [column] IS NULL
So: the above query will update all YEAR column whose value is NULL to 2014
3. INSERT INTO planes (Tailnum, Year, type, Manufacturer, Model, Engines, Seats) VALUES ('N15501',2013,'Fixed wing single engine', 'BOEING', 'A222-101',3,100,NULL)
To insert is very straight foward.
The syntax is:
INSERT INTO [table-name] (column names) VALUES (values)
4. DELETE FROM planes WHERE Tailnum = 'N15501'
To do this, we use the update query which is as follows:
DELETE FROM [table-name] WHERE [column] = [value]
So: The above query will delete the entry in (3) above
differentiate between system software and application software
Answer:
system software is the software which control overall operation of the computer . For eg. Ms.dos ,window 2003 ,etc whereas application software is a software which work on the top of operating system to solve number of problems .For eg. Ms.word,Ms.excel,etc
1.) System software is used for operating computer hardware. On other hand Application software is used by user to perform specific task.
2.) Low level languages are used to write the system software. While high level languages are used to write the application software.
3.) System Software a general purpose software. While application software a specific purpose software.
4.) Without system software, system can’t run. While without application software system always runs.
5.) System software runs when system is turned on and stop when system is turned off. While application software runs as per the user’s request.
6.) System Software programming is complex than application software. Application software programming is simpler as comparison to system software.

Develop a C program that calculates the final score and the average score for a student from his/her (1)class participation, (2) test, (3) assignment, (4) exam, and (5) practice scores. The program should use variables, cout, cin, getline(), type casting, and output manipulators. The user should enter the name of the student and scores ranging from 0 to 100 (integer) for each grading item. The final score is the sum of all grading items. The average score is the average of all grading items.
Answer:
#include <iomanip>
#include<iostream>
using namespace std;
int main(){
char name[100];
float classp, test, assgn, exam, prctscore,ave;
cout<<"Student Name: ";
cin.getline(name,100);
cout<<"Class Participation: "; cin>>classp;
while(classp <0 || classp > 100){ cout<<"Class Participation: "; cin>>classp; }
cout<<"Test: "; cin>>test;
while(test <0 || test > 100){ cout<<"Test: "; cin>>test; }
cout<<"Assignment: "; cin>>assgn;
while(assgn <0 || assgn > 100){ cout<<"Assignment: "; cin>>assgn; }
cout<<"Examination: "; cin>>exam;
while(exam <0 || exam > 100){ cout<<"Examination: "; cin>>exam; }
cout<<"Practice Score: "; cin>>prctscore;
while(prctscore <0 || prctscore > 100){ cout<<"Practice Score: "; cin>>prctscore; }
ave = (int)(classp + test + assgn + exam + prctscore)/5;
cout <<setprecision(1)<<fixed<<"The average score is "<<ave;
return 0;}
Explanation:
The required parameters such as cin, cout, etc. implies that the program is to be written in C++ (not C).
So, I answered the program using C++.
Line by line explanation is as follows;
This declares name as character of maximum size of 100 characters
char name[100];
This declares the grading items as float
float classp, test, assgn, exam, prctscore,ave;
This prompts the user for student name
cout<<"Student Name: ";
This gets the student name using getline
cin.getline(name,100);
This prompts the user for class participation. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)
cout<<"Class Participation: "; cin>>classp;
while(classp <0 || classp > 100){ cout<<"Class Participation: "; cin>>classp; }
This prompts the user for test. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)
cout<<"Test: "; cin>>test;
while(test <0 || test > 100){ cout<<"Test: "; cin>>test; }
This prompts the user for assignment. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)
cout<<"Assignment: "; cin>>assgn;
while(assgn <0 || assgn > 100){ cout<<"Assignment: "; cin>>assgn; }
This prompts the user for examination. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)
cout<<"Examination: "; cin>>exam;
while(exam <0 || exam > 100){ cout<<"Examination: "; cin>>exam; }
This prompts the user for practice score. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)
cout<<"Practice Score: "; cin>>prctscore;
while(prctscore <0 || prctscore > 100){ cout<<"Practice Score: "; cin>>prctscore; }
This calculates the average of the grading items
ave = (int)(classp + test + assgn + exam + prctscore)/5;
This prints the calculated average
cout <<setprecision(1)<<fixed<<"The average score is "<<ave;

Your program should include the following four functions:
check_length - This function should accept a password to evaluate as a parameter and should return a score based on the length of the password. A password that is less than 8 characters long gets a length score of 1. If it is between 8 and 11 characters long (inclusive), it gets a length score of 2. A password that is 12 characters or longer gets a length score of 3.
check_case - This function should accept a password to evaluate and return a case score of 1 or 2. If the letters in the password are all uppercase or all lowercase, the case score should be a 1. If there is a mix of uppercase or lowercase letters (or if there are no letters at all), it gets a case score of 2.
check_content - This function should accept a password to evaluate and return a content score. If the characters are all alphabetic characters, the content score is 1. If the characters include any numeric digits (either all numeric or a mix of letters and digits), the content score is 2. If there are any other types of characters (such as punctuation symbols), the content score is 3.
main - This function represents the main program. It accepts no parameters and returns no value. It contains the loop that allows the user to process as many passwords as desired. It function calls the other functions as needed, computing the overall score by adding up the scores produced by each function. All output should be printed in the main function.
python please
Answer:
def main():
pwd = input("Password: ")
print("Length: "+str(check_length(pwd)))
print("Case: "+str(check_case(pwd)))
print("Content: "+str(check_content(pwd)))
def check_length(pwd):
lent = len(pwd)
if lent < 8:
return 1
elif lent >=8 and lent <= 11:
return 2
else:
return 3
def check_case(pwd):
if(pwd.isupper() or pwd.islower()):
return 1
else:
return 2
def check_content(pwd):
if(pwd.isalpha()):
return 1
elif(pwd.isalnum()):
return 2
else:
return 3
if __name__ == "__main__":
main()
Explanation:
The main begins here
def main():
This prompts the user for password
pwd = input("Password: ")
This calls the check_length function
print("Length: "+str(check_length(pwd)))
This calls the check_case function
print("Case: "+str(check_case(pwd)))
This calls the check_content function
print("Content: "+str(check_content(pwd)))
The check_length function begins here
def check_length(pwd):
This calculates the length of the password
lent = len(pwd)
If length is less than 8, it returns 1
if lent < 8:
return 1
If length is less than between 8 and 11 (inclusive), it returns 2
elif lent >=8 and lent <= 11:
return 2
If otherwise, it returns 3
else:
return 3
The check_case function begins here
def check_case(pwd):
If password contains only uppercase or only lowercase, it returns 1
if(pwd.isupper() or pwd.islower()):
return 1
If otherwise, it returns 2
else:
return 2
The check_content function begins here
def check_content(pwd):
If password is only alphabet, it returns 1
if(pwd.isalpha()):
return 1
If password is only alphanumeric, it returns 2
elif(pwd.isalnum()):
return 2
If otherwise, it returns 3
else:
return 3
This calls the main function
if __name__ == "__main__":
main()
what is output?
a include <iostreom.h>

}
اے
void main ()
{ clrser ()
float x = 5.8
cout<<" \nx="<<x'
sob (x);
Cout <<"\nx="<<x
getch ();
}
Answer:
x=5.8
x=7.8
x=7.8
Explanation:
I repaired the code somewhat (see below).
Since x is passed as a reference variable to the sub function, inside sub() the original variable is modified, so the changed value affects the variable declared in main().
If you would remove the & in sub, this wouldn't happen, and the variable in main would keep its value 5.8.

Description
Military time uses 24 hours for the entire day instead of 12 for am/pm separately. Military time is a 4 digit (base-10) integer with the following rules:
The first two digits show the hour (between 00 and 23) and
The last two digits show the minutes (between 00 and 59)
There is no colon separating hours from minutes.
Military time starts at 0000 in the morning and counts up
When we get to the afternoon, we use 1300 for 1:00 PM and 2300 for 11:00 PM.
When we get to midnight, the hour is 00 (not 24).
TASK: Write a program that reads two times in military format and prints the number of hours and minutes between the two times (See example below).
NOTE: Your program should consider the difference between the times IN THE SAME DAY. For example: The time difference between 2359 and 0000 is 23 hours and 1 minute (NOT 1 minute).
Detailed Requirements
• Compose a written document (MS Word Document) describing your algorithm, feel free include a diagram if you like
• The program should prompt for two times separately, then print the duration of time between (see sample output below).
• The program should check the input for the correct military time format:
. Make sure the hours are between 00 and 23.
. Make sure the minutes are between 00 and 59
. If the validity check fails, it should print an appropriate error and prompt again.
• Your program should use io manipulators to produce military time with leading zeroes. e.g. 9 am should be printed 0900 (not 900).
• More points will be awarded to an implementation that can produce an accurate result regardless of the order of the inputs.
• Do not produce runtime errors that abruptly end your program (crash)
• Include descriptive comments, neat indentation, proper spacing for good readability, and appropriate and consistently named variables.
• Program source should have a comment block at the top with the student name, section, and description of your program.

Explanation:
The python Datetime package is used to manipulate date and time, creating immutable Datetime objects from the various python data types like integer and string. The block of code above is a conditional for-loop statement that gets two user time value inputs and prints out the difference as a string in Military forest time format.
C++ "Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement. Assume simonPattern and userPattern are always the same length.
Ex: The following patterns yield a userScore of 4:
Ex: The following patterns yield a userScore of 9:
simonPattern: RRGBRYYBGY
userPattern: RRGBBRYBGY
Result: Can't get test 2 to occur when userScore is 9
Testing: RRGBRYYBGY/RRGBBRYBGY
Your value: 4
Testing: RRRRRRRRRR/RRRRRRRRRY
Expected value: 9
Your value: 4
Tests aborted.
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
int userScore = 0;
string simonPattern, userPattern;
cout<<"Simon Pattern: "; cin>>simonPattern;
cout<<"User Pattern: "; cin>>userPattern;
for (int i =0; i < simonPattern.length();i++){
if(simonPattern[i]== userPattern[i]){
userScore++; }
else{ break; }
}
cout<<"Your value: "<<userScore;
return 0;
}
Explanation:
This initializes user score to 0
int userScore = 0;
This declares simonPattern and userPattern as string
string simonPattern, userPattern;
This gets input for simonPattern
cout<<"Simon Pattern: "; cin>>simonPattern;
This gets input for userPattern
cout<<"User Pattern: "; cin>>userPattern;
This iterates through each string
for (int i =0; i < simonPattern.length();i++){
This checks for matching characters
if(simonPattern[i]== userPattern[i]){
userScore++; }
This breaks the loop, if the characters mismatch
else{ break; }
}
This prints the number of consecutive matches
cout<<"Your value: "<<userScore;
