C Programming – Introduction to C Language

C programming is a language developed by AT & T’s Bell Laboratories of USA in 1972. C programming was designed and written by a man named Dennis Ritchie. C programming is reliable, simple and easy to use. C has survived for more than 3 decades. C programming language is a base to learn different programming language.

If you want to learn C++ or JAVA, without the knowledge of C programming it becomes very difficult to learn these programming languages. Many major components of popular operating systems like Windows, UNIX, LINUX is still written in C.

Nothing beats C programming in terms of speed of execution.

Before starting with the programming, let’s have a look at the C programming Character set.

    Sorry to prove you wrong, but assembly runs faster than C. Takes loads longer to code, though.
    Trying this site ’cause I can read C, but not write it, and after VB.net and C#, i thought I might as well try C
