Section 6.6 Remainders

A remainder is the amount that “remains” after division takes place. The mathematical operation that produces this remainder is called the modulo operation. Note that this is the fractional remainder, not a decimal value, so the result of the modulo operation should always be an integer. For example, the remainder when dividing 29 by 3 is 2 since 3 goes into 29 just 9 times and 29 - 9*3 = 2.

Suppose we want to know the remainder of the division of one integer by another. Can we do this with our current programming knowledge?

#include <stdio.h>

int main(void) {

    int num, denom, remainder;
    
    printf("Please enter a numerator and a denominator, separated by a space: ");
    scanf("%d %d", &num, &denom);
    
    remainder = /* please complete this line */
    
    printf("The remainder, when dividing %d by %d, is %d.\n", num, denom, remainder);
    
    return(0);
}
