Cpp Program to find whether a number is prime or composite.

This is a basic program in Cpp which checks whether the number is prime number or composite number.
A number is said to be prime if it is divided by 1 and itself other numbers are called composite however the numbers 0 and 1 are neither prime or composite.

PROGRAM :

#include <iostream>

using namespace std;

int main()
{
    int i,n;
    cout << "Enter any number : \t" << endl;
    cin  >> n ;

    if(n == 0 || n == 1)
        cout << n << " is neither PRIME nor COMPOSITE" << endl;

    for ( i = 2 ; i <= n-1 ; i++ )
    {
      if ( n%i == 0 )
      {
         cout << n << " is COMPOSITE number" << endl;
         break;
      }
    }
    if ( n == i )
      cout << n << " is PRIME number" << endl;

    return 0;
}

OUTPUT :

Cpp - Prime Or Composite 

Cpp  - Prime Or Composite

Cpp - Prime Or Composite
