Thread: A getchar problem

This is stupid code i made.
There is a problem.If i delete one of the "getchar()'s" the program doesn't work.
Can anyone explain why?

Code:

#include <stdio.h>
int main (void)
{
    int a,b,c;
    float d;
    
    printf("How many apples did you eat?");
    scanf("%d",&a);
    if(a>0){
            printf("How many were there?");
            scanf("%d",&b);
            printf("How many apples?");
            scanf("%d",&c);
            d=b/a;
            if (a>d){
                     printf("You are fat!");
                    }            
            }
    else
        printf("Did you drink?");
getchar();
getchar();
return 0;
}

The program should still work, it will just quit before you get a chance to see the output. The first getchar() absorbs the \n character from when you hit return at your scanf(), the second then waits for another character. Without the second getchar, the program just ends without pausing.
