C and CPP are designed basically for making the machine understand the end users (the people uses the computer) instructions. These are classified as high-level programming language which was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. Since UNIX was full of command based language it was not easy to operate. So to overcome those high level languages such as C and C++ was developed. C was originally first implemented on the DEC PDP-11 computer in 1972. In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available description of C, now known as the K&R standard. The UNIX operating system, the C compiler, and essentially all UNIX application programs have been written in C. C has now become a widely used professional language for various reasons: · Easy to learn · Structured language · It produces efficient programs · It can handle low-level activities · It can be compiled on a variety of com...
