The C Programming Language
The C language by far is the most popular programming language. C originated at Bell Labs while writing the first UNIX operating system for a DEC PDP-7 computer with only 8K bytes of memory by the researcher. C not just serves as an operating system language but all other programming languages are derived directly or indirectly from C programming concepts. It is one simple and powerful language that has been ported to many platforms. C is a good choice for system-level programming and is still stable. Yet, if one takes a more in depth look at C, one realizes that it is rather weak and has an extremely small vocabulary.
