C Exercises: Test two integers are multiply or not

Check if two integers are multiples of each other

Write a C program that takes two integers and tests whether they are multiplied or not.

In science, a multiple is the product of any quantity and an integer. In other words, for the quantities a and b, we say that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.

Sample Solution:

C Code:

#include <stdio.h>
int main () {

    // Declare unsigned short integer variables x, y, and multi
    unsigned short int x, y, multi;

    // Prompt the user to input two integers
    printf("Input two integers: \n");

    // Read the input values for x and y
    scanf("%hd %hd", &x, &y);

    // Check if x is greater than y
    if (x > y){

        // Calculate the remainder when x is divided by y
        multi = x % y;

        // Check if the remainder is zero
        if ( multi == 0){
            printf("Multiplies\n");
        }
        else{
            printf("Not Multiplies\n");
        }
    }
    else{
        // Calculate the remainder when y is divided by x
        multi = y % x;

        // Check if the remainder is zero
        if (multi == 0){
            printf("Multiplies\n");
        }
        else{
            printf("Not Multiplies\n"); 
        }
    }
}

Sample Output:

Input two integers:
3
9
Multiplies
