**The Program in C that Calculates the remainder of** **2 numbers without using % operator is given below:**

```
#include <stdio.h>
int main() {
int num1, num2, remainder;
printf("Enter the dividend number: ");
scanf("%d", &num1);
printf("Enter the divisor number: ");
scanf("%d", &num2);
remainder = num1 - (num1 / num2) * num2;
printf("The remainder when %d is divided by %d is: %d", num1, num2, remainder);
return 0;
}
```

## Output:

Enter the dividend number: 81

Enter the divisor number: 9

The remainder when 81 is divided by 9 is: 0

## Pro-Tips💡

This program takes input of two integers and uses the mathematical operation of subtraction to calculate the remainder when num1 is divided by num2 without using the modulus operator(%).

It uses the property of modulus operator, which is the remainder is given by num1 – (num1 / num2) * num2.

You can also use the ternary operator to simplify the code
