C (pronounced "see") is a general purpose programming language developed by Bell Telephone in the early 1970s. It is known as a highly portable language; a C program can be written once and then compiled with either no or minimal changes on most of the commonly used computer systems.
The derived languages C++ ("C plus plus") and C# ("C sharp") have also been used to create utility programs.
