C is a procedural programming language. It was initially developed by Dennis Ritchie in 1972. It was mainly developed as a system programming language to write an operating system. The main features of the C language include low-level memory access, a simple set of keywords, and a clean style; these features make C language suitable for system programming like an operating system or compiler development.
Many later languages have borrowed syntax/features directly or indirectly from the C language. Like the syntax of Java, PHP, JavaScript, and many other languages are mainly based on the C language. C++ is nearly a superset of C language (Few programs may compile in C, but not in C++).
