Write a C++ Program For Find Factorial

#include <iostream>
using namespace std;

int main() {
    unsigned int n;
    unsigned long long factorial = 1;
    cout << "Enter a positive integer: ";
    
    cin >> n;
    for(int i = 1; i <=n; ++i) {
        factorial *= i;
    }
    cout << "Factorial of " << n << " = " << factorial;
    
    return 0;
}


Output

Enter a positive integer: 12
Factorial of 12 = 479001600
