Write a C++ program creates two classes find maximum from given two numbers using constructor

Assignment 24

Write a C++ program using class which contains two data members of type integer. Create and initialize the object using default constructor, parameterized constructor and parameterized constructor with default value. Write a member function to display maximum from given two numbers for all objects.

Program Code for run:

#include <iostream>

using namespace std;

                a2 = a1;

            n1 = a1;

            n2 = a2;
