The UNIX operating system, the C compiler, and essentially all UNIX applications programs have been written in C. The C has now become a widely used professional language for various reasons. o       Easy to learn o       Structured language o       It produces efficient programs. o       It can handle low-level activities. o       It can be compiled on a variety of computer platforms.
