C++ Program to Check Prime Number Using Function

In this tutorial you will learn about the C++ Program to Check Prime Number Using Function and its application with practical example.

C++ Program to Check Prime Number Using Function

In this tutorial, we will learn to create a C++ program that will Check Prime Number Using functions using C++ programming.

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C++ programming topics:

  • Operators in C++ Programming.
  • Basic Input and Output function in C++ Programming.
  • Basic C++ programming.
  • For loop in C++ programming.
  • Conditional Statements in C++ programming.
  • Arithmetic operations in C++ Programming.

Program to Check Prime Number Using Function:-

A prime number is a number that is only divisible by only one number or by itself only. In c++ programming, it is possible to take numerical input from the user and check if that number is Prime Number or not with the help of a very small amount of code.

In this program, we will take a number in the input from the user to check if it’s prime or not.

With the help of this program, we can Check Prime Number Using Function.

Algorithm:-

Program to Check Prime Number Using Function:-

Output:-

In the above program, we have first initialized the required variable.

  • no= it will hold the integer value of the input.
  • i = it will hold the integer value.
  • flag = it will hold the integer value.

Input message for the user for the integer value.

Program Logic Code.

Printing output prime number or not.

In this tutorial we have learn about the C++ Program to Check Prime Number Using Function and its application with practical example. I hope you will like this tutorial.
