C programming is one of the most popular programming languages in the world, if not the most popular. It is used everywhere. Whether you're using a modern operating system like Mac OS X or Linux, using a game console like the Nintendo Wii, or writing software for embedded systems, it is probably written in C. C is also popular in academia and industry, where many programmers have to know it. C programming language was developed by Dennis Ritchie at AT&T Bell Labs in 1972. It has undergone many changes since then; the most recent standard is the ANSI Standard for C (usually called ANSI C). The C programming language has spawned a large family of dialects and other languages influenced by it.

Programming languages can be used to create programs to control the behavior of a machine, to express algorithms precisely, or as a mode of human communication. The Cprogramming language is very low-level (close to the hardware) and thus is harder to learn than a higher level programming language. This is a practice course, containing just a collection of Cprogramming exercises. If you are new to C programming and want to have practice exercises, this course is for you.
