Introduction-

The C++ mod operator is something that returns the remainder of a division of one number by another. When we try to divide two integer numbers we are going to have an equation that will look similar to the below-mentioned things.

  1. A/B= Q Remainder and R where.
  2. A is always the dividend whereas B is always the divisor.
  3. Q is always the quotient and R is always the remainder.

But do you know that sometimes we are always interested in what the remainder is when A and B are divided? Hence, in these such cases, there is an operator and that is called the mod operator C++.

Using the same A, B, Q, and R as above we are going to have A mod B= R. We are going to say that this is A modulo B and is equal to R where B is referred to as modulus. However, there are multiple uses of C++ modulus operator such as telling if a factor of another number or not. It can also there for generating a random number or for finding an even or odd number as well. The modulus operator % can only be used with integer numbers and are always going to have integer answers. Below is something that is going to show a different set of numbers.

Modulus C++ Operator-

Taking a simple authentic problem as shown, how are you going to compute this in a programming language such as C or C++ modulus language? The C and C++ language is having an in-build mechanism, the C mod operator (%) is there to compute the remainder that will result from performing integer division. You will have to consider the following program which is going to take the number from the user and that will calculate the remainder of the number divided by 3.

Now, let’s take another example, which will calculate whether the input number is a leap year or returns 1 otherwise returns 0. You can also find even the number is odd or even through the mod in C++ operator. This can be easily be there by asking about the remainder of the number when divided by 2.

std::modulus-

The modulo C++ standard library is having something of std:: C programming modulus. When T is not known and there leaves the parameter type and deduced return type. Binary function object class whose call returns the result of the modulus operation is there between its two arguments. For example, the C++ modulo following code finds whether the number there is an array and odd or even through the operator.

What are the real-life uses of this modulus operator C++ language?

Knowing the remainder of the division is very much useful in real-life situations. Have a look at the examples, to know better.

Example 1:  Find hours, minutes, and seconds from the number of seconds.

This is one of the simple situations where people are with a number of seconds and this is the place where the modulo operators can be there to find the hours, minutes, seconds. Go and try it out if you want to know about the proper time shape.

Example 2: Rotating through limited options.

In some of the cases modulus operator in C. We is there with a limited number of options that we can go through. For example, we are having three employees and one of them is having a night shift daily. Here is the place where we can use a modulo operator. To walk through an array of days in a rotating loop.

Hence, this is all that you should know about C++ mod operator. To learn something more let us know through the comments down below.
