C Program to Check if a Number is Divisible By Second Number or not.

Program

#include<conio.h>
void main()
{
	int num1, num2;

    printf("Enter first number\t:");
    scanf("%d",&num1);
    printf("Enter second number\t:");
    scanf("%d",&num2);

    if(num2>num1)
    {
        printf("\nSecond number can not be greater by first number");
    }
    else
    {
		if((num1%num2)==0)
		{
	            printf("\nSecond number is a factor of first number");
		}
	        else
		{
		    printf("\nSecond number is not a factor of first number");
		}
    }

    getch();
}

Output

********** Run1 ********** 

Enter first number      :20
Enter second number     :5

Second number is a factor of first number


********** Run2 ********** 

Enter first number      :20
Enter second number     :6

Second number is not a factor of first number
