Question

USE while structure to create and control a loop

Professor James asked you to write a letter grade program for him.  The program should ask for score and display the appropriate letter Grade base on the following grading policy. Run the programs for 5 Students with grade of (90, 72,89,56, 62).

If  Grade >= 90   print  “A” and “excellent”

  Grade >= 80  print “B”  and “very Good”

  Grade >= 70  print  “C”  and “Good”

  Grade >= 60  print “D” and “passed”

  Below  60 is “F”

Submit the following :

1) Algorithm and flowchart    50

2) Source code   40

3) output           10

C++

Answer 1

Code

#include<iostream>

using namespace std;

int main()

{

//declare variables

int i=0;

int Score;

while(i<5)//while loop till i is less then 5

{

//prompt user for asking the score

cout<<"Enter the "<<(i+1)<<" student's Score: ";

//store in score variable

cin>>Score;

cout<<"Letter Grade : ";

if(Score>=90)//check if the score is greater then or equals to 90 then print A

cout<<"A excellent"<<endl;

else if(Score >= 80 ) //check if the score is greater then or equals to 80 then print B

cout<<"B very Good"<<endl;

else if(Score >= 70 ) //check if the score is greater then or equals to 70 then print C

cout<<"C very Good"<<endl;

else if(Score >= 60 ) //check if the score is greater then or equals to 60 then print D

cout<<"D very Good"<<endl;

else//else it is less then 60 and print Fs

cout<<"F"<<endl;

cout<<endl<<endl;

i++;

}

return 0;

}

output

algorithm

Input: Student Score

1. if (the score is greater then or equal to 90)

then

print the Grade is A Excellent

End If

2. if (the score is greater then or equal to 80)

then

print the Grade is B Very Good

End If

3. if (the score is greater then or equal to 70)

then

print the Grade is C Good

End If

4. if (the score is greater then or equal to 60)

then

print the Grade is D Passed

End If

5. if (the score is less then to 6 0)

then

print the Grade is F

End If

End
