What is C?

C is a programming language developed at Bell Laboratories of USA in 1972.

Designed and written by a man named Dennis Ritchie.

Many programmers preferred C to older languages like FORTRAN, or the newer ones like Pascal.

C is reliable, simple and easy to use.

C has been already superseded by languages like C++ and Java, so why bother to learn C today

What C is Indispensable?

I believe that nobody can learn C++ or Java directly. One should first learn all the language elements very thoroughly using C language before migrating to C++, C# or Java.

C++, C# or Java make use of a principle called Object Oriented Programming (OOP) to organize the program. But even while using this organizing principle you would still need a good hold over the language elements of C and the basic programming skills.

Though many C++ and Java based programming tools and frameworks have evolved, you would be still required to use the core C language elements.

Major parts of popular operating systems like Windows, UNIX, Linux is still written in C. This is because even today when it comes to performance (speed of execution) nothing beats C. Moreover, if one is to extend the operating system to work with new devices one needs to write device driver programs. These programs are exclusively written in C.

What C is Indispensable?

Mobile devices like cellular phones and palmtops, common consumer devices like microwave oven, washing machines and digital cameras are getting smarter by the day. No wonder that such programs are written in C.

Professional 3D computer games. The essence of all such games is speed. Many popular gaming frameworks have been built using C language.

C closely interact with the hardware devices.
