 Find the remainder without using % (Modulus operator)?

#include <stdio.h>

int main()

{

int num,div,rem=0;

printf("enter the number and divisor\n");

scanf("%d %d",&num,&div);

if(num!=0 && div !=0)

{

rem=num/div;

rem*=div;

rem=num-rem;

printf("without modulus= %d\n",rem);

}

printf("with modulus\t=%d",num%div);

}

output:-

enter the number and divisor

25 7

without modulus= 4

with modulus =4
