#include<stdio.h>
#include<iostream.h>
class World
{
public:
World()
{
printf("Hello world");
}
}

world w1;


Here the object is declared globaly.so when the object is
defined it will call the constructor of that & that will
display the "hello world". no need to write main. as it is
global.

Why isn't any of this standardized in c? Any real program has to do some of these things.
