Modulus Operator in C

The modulus operator is represented by the % symbol. It is used to find the remainder when one integer is divided by another. The modulus operator is particularly useful when you want to work with the remainder of a division operation.

Here’s the basic syntax of the modulus operator:

result = dividend % divisor;

• dividend: The number you want to find the remainder of (the numerator).
• divisor: The number you are dividing by (the denominator).
• result: The remainder after dividing dividend by divisor.

Here are a few examples of how the modulus operator is used:

#include <stdio.h>

int main() {
    int dividend = 10;
    int divisor = 3;
    int result;

    // Calculate the remainder
    result = dividend % divisor;

    printf("The remainder of %d divided by %d is %d\n", dividend, divisor, result);

    return 0;
}

In this example, dividend is 10, divisor is 3, and result will be assigned the value 1 because 10 divided by 3 is 3 with a remainder of 1.

Here’s another example:

#include <stdio.h>

int main() {
    int dividend = 17;
    int divisor = 5;
    int result;

    // Calculate the remainder
    result = dividend % divisor;

    printf("The remainder of %d divided by %d is %d\n", dividend, divisor, result);

    return 0;
}

In this case, dividend is 17, divisor is 5, and result will be assigned the value 2 because 17 divided by 5 is 3 with a remainder of 2.

The modulus operator is frequently used in programming for various purposes, including checking for even or odd numbers, performing cyclic calculations, and finding patterns in data.
