# C Exercises: Reads in two integers and check whether the first integer is a multiple of the second integer

## C Basic Declarations and Expressions: Exercise-73 with Solution

Write a C program that reads two integers and checks whether the first integer is a multiple of the second integer.

**Sample Input:** 9 3

**Sample Solution:**

**C Code:**

```
#include<stdio.h>
// Function to check if n1 is a multiple of n2
int is_Multiple(int n1, int n2)
{
return n1 % n2 == 0;
}
int main()
{
int n1, n2;
// Prompt for user input
printf("Input the first integer : ");
scanf("%d", &n1);
printf("Input the second integer: ");
scanf("%d", &n2);
// Check if n1 is a multiple of n2 and print result
if(is_Multiple(n1, n2))
printf("\n%d is a multiple of %d.\n", n1, n2);
else
printf("\n%d is not a multiple of %d.\n", n1, n2);
return 0;
}
```

Sample Output:

Input the first integer : Input the second integer: 9 is a multiple of 3.
