Interview Question: Print 'Hello World' without semicolon

Write a program in C language which does not have even a single semicolon, but prints 'Hello World'.

Semicolon is used to terminate a statement in C language, but null statement can be written in two ways:

;   // Empty or NULL Statement
{}  // Empty of NULL Statement

The below program uses this fact, to print 'Hello World without having any semicolon in it:

#include <stdio.h>

int main()
{
     while( ! printf("Hello World") )
     {
     }
}

Output:
  Hello World

Note that printf returns the number of characters printed. In this case ptintf will return 11 (including the space character). 11 in C language is true, and control will not enter loop even once (Hence 'Hello World' will be printed only once).
