Write a C++ Program to find Factorial of a number using classinputEnter a number: 5outputBelow is the input and output of the provided C++ program to find the factorial of a number using a class:Input:Enter a number: 5 Output:Factorial of 5 is: 120

Sure, here is a simple C++ program that calculates the factorial of a number using a class:

#include<iostream>
using namespace std;

class Factorial {
    int n, fact = 1;

public:
    void input() {
        cout << "Enter a number: ";
        cin >> n;
    }

    void calculate() {
        for(int i = 1; i <= n; i++) {
            fact = fact * i;
        }
    }

    void display() {
        cout << "Factorial of " << n << " is: " << fact << endl;
    }
};

int main() {
    Factorial obj;
    obj.input();
    obj.calculate();
    obj.display();
    return 0;
}

In this program, we have a class named Factorial with three methods: input(), calculate(), and display(). The input() method takes the number as input from the user, the calculate() method calculates the factorial of the number, and the display() method displays the factorial of the number.
