Episode 1: C programming Overview

Execution of C Program :

C program executes in following 4 (four steps).

1. Creating a program :

An editor like “Turbo C 4.5 or Borland or Dev C++” is used to create a C program. This file contains a source code which consists of executable code. The file should be saved as '*.c' extension only.

2. Compiling the program :

The next step is to compile the program. The code is compiled by using compiler. Compiler converts executable code to binary code i.e. object code.

3. Linking a program to library :

The object code of a program is linked with libraries that are needed for execution of a program. The linker is used to link the program with libraries. It creates a file with '*.exe' extension.

4. Execution of program :

The final executable file is then run by dos command prompt or by any other software.
