how to modulo in c without use the operator

To perform modulo in C without using the modulo operator, you can use the following steps:

1. Divide the dividend by the divisor using the division operator (/). This will give you the quotient.
2. Multiply the quotient by the divisor using the multiplication operator (*).
3. Subtract the product from the dividend. This will give you the remainder.

Here's an example code snippet that demonstrates this process:

#include <stdio.h>

int modulo(int dividend, int divisor) {
    int quotient = dividend / divisor;
    int product = quotient * divisor;
    int remainder = dividend - product;
    return remainder;
}

int main() {
    int dividend = 17;
    int divisor = 5;
    int result = modulo(dividend, divisor);
    printf("The remainder of %d divided by %d is %d\n", dividend, divisor, result);
    return 0;
}

In this example, the modulo function takes two integers as input: dividend and divisor. It performs the steps described above and returns the remainder. The main function demonstrates the usage of the modulo function by calculating the remainder of 17 divided by 5.

Please note that this approach assumes positive integers for both the dividend and divisor. If negative numbers are involved, additional steps may be required to handle the sign of the remainder.
