The History Of TURBO C?

C stands for COMBINED PROGRAMMING LANGUAGE. Sometimes called SYSTEM PROGRAMMING LANGUAGE or SPL. C parallels with UNIX in 1969, by Bell Laboratories that sought an alternative to the Multics operating system for PDP-7 computer. The original version of Multics operating system was written in assembly language.

The reason why the language is called C is that it is the successor to the language called B which was developed by Ken Thompson in 1970 while working on DEC PDP-7. B was the successor the language called BCPL (Basic Combined Programming Language) which was developed by Martin Richards.

The C Language was designed in 1972 by Dennis Ritchie and first implemented at Bell Laboratory using DEC PDP-11 computer.

In 1978 Brian Kernighan and Dennis Ritchie wrote the famous book called THE C PROGRAMMING LANGUAGE.

C is often called a Middle Level Language but has a functionalism of a high-level language and assembly language. C has only 32 keywords (27 from Kernighan and Ritchie standard and 5 added by the ANSI Standardization committee).

Programming is a series of individual instructions to the computer that collectively perform a meaningful task. It is the act of writing or coding computer instructions.

Program Source Code is the finished encoded instructions.

Programmer is the one who write the computer program and the first lady programmer is Lady Augusta "Ada" Byron.

Translator is use to transform the source code into a machine language that the computer can understand.

Linker is use to adjust the translated source file so that the program will run. Linking is usually distinct from the compiling process on a machine running MS-DOS.
