C Programming Language - Tutorial

---

C is general purpose, procedural programming language developed in 1972 by Dennis M. Ritchie at the Bell Telephone Laboratories. C is the most widely used computer language. it has low level access to memory, and provide language constructs that map efficiently to machine instructions, and require minimal runtime support.

C has structured programming and allows lexical variable scope and recursion. Its static type system prevents unintended operations. all executable code is contained within functions. Function parameters are always passed by value. Pass-by-reference is simulated in C by explicitly passing pointer values.
