C++ Program to Check Whether a Number is Prime or Not

In this tutorial you will learn about the C++ Program to Check Whether a Number is Prime or Not and its application with practical example.

C++ Program to Check Whether a Number is Prime or Not

In this tutorial, we will learn to create a C++ program that will Check Whether a Number is Prime or Not 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 Whether a Number is Prime or Not:-

In c++ programming, it is possible to take numerical input from the user and check if that number is Prime Number or not. The prime number means a number that is only divisible by itself.

With the help of this program, we can Check Whether a Number is Prime or Not.

Algorithm:-

Program to Check Whether a Number is Prime or Not:-

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 Whether a Number is Prime or Not and its application with practical example. I hope you will like this tutorial.
