#include <iostream>
using namespace std;
class Demo
{
public:

    int main(char *a)
    {
        cout << a << "\n";
        return 0;
    }

    int main(int a)
    {
        cout << a << "\n";
        return 0;
    }

    int main(int a ,int b)
    {
        cout << a << " " << b;
        return 0;
    }
};
int main()
{
    Demo ob;
    ob.main("Overloading of main");
    ob.main(3);
    ob.main(7, 8);
    return 0;
