C programming: introduction

C is not just letter C, It is a programming language. what is a programming language?

a programming language is what a program can understand. It only understand one kind of spelling per command. in other words it's a man that only understand one language. in addition, it can only understand PERFECT spelling no misspelling must be done or else it will not run properly.

It is old in history but still useful, it is still used in some( or many correct me if I am wrong ) I am not sure but I think world of warcraft runs on it. yahoo messenger runs on Visual C++

its working interface is sure doesnt look like what you can imagine. It has blue background and yellow foreground (like in the boot menu[when you press delete when the system starts)
