Output of any C Program is converted to an EXE file in Windows Systems so that you can execute the file and get the desired output everytime. In this tutorial we shall teach you what is the meaning of Building a C Program.

Note: Any C program is named with a .C File Name Extension. Usually Editors like Eclipse or Turbo C are used to type a C Program. A C Editor is just like a Notepad software that allows us to Type a new program or edit an existing program. It can not compile or assemble any code.

A Preprocessor in a C programming language is a Program that processes source code of a C program, expanding Macro Definitions, File Inclusions and more.

Only through Preprocessor directives, you are able to include library files in your C program.

Preprocessing in C happens before compilation. Part of the Source code is replaced with Preprocessing expressions where ever encountered. So the size of Total code increases before passing to the Compiler.
