Another World

Actually learning programming is a start for going into another world. And this is the reason for writing our first program with a name "Hello, world.".

But this is not the only reason and actually the main reason of this work turns to 1973 when Brian Kernighan (the writer of a famous book in C language with name "A Tutorial Introduction to the Programming Language B") used "Hello, world" in his program. And when he was asked that why he uses this text, he answered that I forgot. And since then, no one can prove why it has become so popular.
