c language concepts

C (pronounced /siː/, like the letter C) is a general-purpose computer programming language developed between 1969 and 1973 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system.

Although C was designed for implementing system software, it is also widely used for developing portable application software.

C is one of the most popular programming languages of all time and there are very few computer architectures for which a C compiler does not exist. C has greatly influenced many other popular programming languages, most notably C++, which began as an extension to C.

This C blog page is not intend to provide a complete C  language, but instead I will give you the important concepts and will try to explain the toughest concept in C that developers and the students are having. I will keep on posting to this. Please add you comments at any moment if you feel something went wrong, of-course I am human being so mistakes can happen.
