Modulus

The modulus operator in C++ is represented by the percent sign (%). It calculates the remainder of the division of one number by another. Here are the steps involved in using the modulus operator in C++:

1. The modulus operator requires two operands - a dividend and a divisor. The dividend is the number being divided, and the divisor is the number by which the dividend is divided.

2. The modulus operator is placed between the dividend and the divisor. The syntax for using the modulus operator is: dividend % divisor.

3. When the modulus operator is applied, the division is performed, and the remainder is returned as the result. For example, if the dividend is 10 and the divisor is 3, the division would result in a quotient of 3 and a remainder of 1. Therefore, the modulus operator would return 1.

4. The result of the modulus operator is always a whole number between 0 and the divisor minus 1. For example, if the divisor is 5, the possible results of the modulus operator would be 0, 1, 2, 3, or 4.

5. The modulus operator can be used with both integer and floating-point numbers in C++. However, when used with floating-point numbers, the result may not be exact due to the inherent imprecision of floating-point arithmetic.

6. The modulus operator can be useful in various scenarios, such as determining whether a number is even or odd, checking divisibility, or cycling through a set of values.

That's a brief explanation of the modulus operator in C++. Let me know if you have any further questions.
