Write a C++ program to find Reverse of a Number using class.inputEnter a number: 12345output54321

Sure, here is a simple C++ program that uses a class to reverse a number:

#include<iostream>
using namespace std;

class ReverseNumber {
    int num, rev;
public:
    ReverseNumber() : num(0), rev(0) {}

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

    void reverse() {
        while(num != 0) {
            int digit = num % 10;
            rev = rev * 10 + digit;
            num /= 10;
        }
    }

    void display() {
        cout << "Reversed Number: " << rev << endl;
    }
};

int main() {
    ReverseNumber rn;
    rn.input();
    rn.reverse();
    rn.display();

    return 0;
}

In this program, we have a class ReverseNumber with two data members num and rev. The input() member function is used to take the number as input from the user. The reverse() member function is used to reverse the number. The display() member function is used to display the reversed number. In the main() function, we create an object of the class and call these functions.
