This session is how to check the number is prime or not in c++ Programming. Here use of while loop in c++ programming with Example
This c++ language programming is free all type of errors like the compiler and runtime errors and this programming is tested to compile and then run the program code.
Here is only programming code with the output. This programming output is customized to understand easily.

How to Find the prime number in c++ Programming?

#include <iostream>
#include <cmath>
using namespace std;
class Newprime {
public:
    int n;
      void isprime(int n) {
        int i, m = 0, f = 0;
         m = n / 2;
        if (n == 0 || n == 1) {
            cout << n <<” is not prime number”;
        } else {
            for (i = 2; i <= m; i++) {
                if (n % i == 0) {
                    cout<< n <<” is not prime number”;
                    f = 1;
                    break;
                }
            }
            if (f == 0) {
                cout<< n <<” is prime number”;
            }
        }
    }
}
int main() {
        Newprime o ;
        o.isprime(3);
        o.isprime(4);
        o.isprime(5);
return 0;
    }
}

Output: 3 is prime number
4 is not prime number
5 is prime number
