Confused about Loops (Beginner Question)

[Sam Liew]

I believe, I need two loops for this..but I just can't make it out no matter how hard I try. So I guess I need help!


Here is the code...:

#include <stdio.h>
#include <stdlib.h>


int main()
{
    int counterH = 0;
    int counterN = 0;
    int mark;
    int confirmExit;


    printf("Please input student mark: ");
    scanf("%d", &mark );


       while ( mark <= 100 )
        {
            if ( mark >= 85 )
                {
                puts ("H");
                counterH++;
                }


            else if ( mark >= 75 )
                puts ("D");


            else if ( mark >= 65 )
                puts ("P");


            else if ( mark >= 50 )
                puts ("C");


            else if ( mark >=  0 )
                {
                puts ("N");
                counterN++;
                }
            
            printf("Please input student mark: ");
            scanf("%d", &mark );
        }
}/* End Main*/

So the problem here, is that I don't know how to insert the other condition which is to exit if the user wants to.


Here's the full question:


1) get one student’s mark (keep asking for input if the input is more than 100)
2) decide and display which grade the mark is in ( make a series of if / else decisions)
3) add 1 (one) to the corresponding counter for grade HD and grade N
4) ask if this is the last student
5) if not the last student, return to the start to get the next student’s mark


I got (1),(2) and (3) right. I don't know how to deal with (4) and (5) =(


I appreciate all the help!

What about putting a BIG

do {
//all your other code goes in here
}while(confirmExit==0);

around all the other code you have? This is for #4.

Do you know how to use functions? the code would be easier to split into parts relevant to different tasks

int answer;
do
{
   int mark = getOneStudentMark(); /* do 1) and 2) inside that funtion */

   /* do 3) here */

  answer = IsThisLastStudent() /* do 4) inside this function and return 1 is yes and 0 is no */
} while (answer);
