Write a program to find the factorial of a number using class & object

#include<iostream>

using namespace std;

class Test {

public:

    int factorial(int x) {

        int i, f = 1;

        for (i = 1; i <= x; i++) {

            f = f*i;

        }

        return f;

    }

};

int main() {

    int x, f;

    cout << "Enter a number:";

    cin >> x;

    Test obj;

    f = obj.factorial(x);

    cout << "Factorial is:" << f;

    return 0;

}

 

Output--

Enter a number:7

Factorial is:5040

#include<iostream> using namespace std; class Test { public: int factorial(int x) { int i, f = 1; for (i = 1; i <= x; i++) { f = f*i; } return f; } }; int main() { int x, f; cout << "Enter a number:"; cin >> x; Test obj; f = obj.factorial(x); cout << "Factorial is:" << f; return 0; }
