C is what is called a compiled language. This means that once you write your C program, you must run it through a C compiler to turn your program into an executable that the computer can run (execute). The C program is the human-readable form, while the executable that comes out of the compiler is the machine-readable and executable form.
To type your C program you need another program called Editor. Once the program has been typed it needs to be converted to machine language (0s and 1s) before the machine can execute it. To carry out this conversion we need another program called Compiler.
On compiling the program its machine language equivalent is stored as an EXE file on the disk. This file is called an executable file.
Steps in creating executable file:
A compiler is a program that converts C code into executable machine code. Popular compiler includes:
Many programmers prefer and recommend using an Integrated development environment (IDE) instead of a text editor. An IDE is a suite of programs that developers need, combined into one convenient package, usually with a graphical user interface. These programs include a text editor, linker, project management and sometimes bundled with a compiler and debugger. Popular IDE includes:
GCC:
The most frequently used and free available compiler is the GNU C/C++ compiler. To check whether GCC is installed on your LINUX or UNIX system, enter the following command from the command line.
If you have GNU compiler installed on your machine, then it should print a message as follows −
If GCC is not installed, then you will have to install it yourself using the detailed instructions available at http://gcc.gnu.org/install/
To install GCC on Windows, download MinGW from www.mingw.org. Add the bin subdirectory of your MinGW installation to your PATH environment variable, so that you can specify these tools on the windows command line by their simple names.

Steps in creating executable file:
- Editing – Create/Modify program source code. It creates source file (*.c).
- Compiling – Generate machine instructions. It creates object file (*.obj).
- Linking – Link in libraries. It creates executable file (*.exe).
- Executing – Run program.
A compiler is a program that converts C code into executable machine code. Popular compiler includes:
