 Program to Find Factorial of a Number in C++ Language

#include <iostream>

using namespace std;

int main()

 {

    int n;

    int fact = 1;

    cout << endl << "Enter a positive number: ";

    cin >> n;

    if (n < 0)

        cout << endl << "Error";

    else 

{

        for(int i = 1; i <= n; ++i)

         {

            fact *= i;

         }

     cout << endl << "Factorial of " << n << " = " << fact << endl;

 }

    return 0;

}

इस कोड को हमने CODEBLOCK पर बना कर run किया है
