How to print "Hello C++" with empty main() in C++? Without using class.

Answer 1

• Define a class and in the constructor print "Hello C++"
• Instantiate the class at the time of the definition so that it executes before the main.

Sample code

#include <iostream>
using namespace std;

class MyClass
{
        public:
                MyClass()
                {
                        cout << "Hello C++";
                }
} myclass;

int main()
{

}
