[h=2]Hello world program in c[/h] We may store "hello world" in a character array and then print it.

If you're interested, I have a lot of code I wrote years back that deals with various networking protocols using raw sockets (assuming you're on linux).

This is just the simplest and basic program in C++. You have to go in functions loops, nested, while and if else ladder. Try to do programming in daily basis.

You could also declare a typedef so that you can use the word "string" instead of having to make a char array every time.

this is pretty basic. Increase the difficulty level and go advance. Only then will you be able to truly accomplish something.

Why the heck store it in an array?

EDIT: OK got it now, I didn't notice that char data type.

Well, using char array is pretty useless, you could just use a string type variable.

Well, you are doing a good job and can you please tell me which compiler are you using to execute the program because i write the same code but DEV C++ compiler is not working on my notebook.

As a compiler BerliOs compiler is good, with that use code blocks IDE

I am student of computer science and these kinds of small programs i daily write in my programing class. I use the Dev C++ compiler to execute the program and if you are familiar with other compiler then mention here.
