Necessary Steps to prepare a C program for Execution

The following necessary steps are taken to prepare a C program for execution:-

• Creating & Editing C program
• Saving C program
• Compiling c program
• Linking c Program
• Loading c Program
• Executing c program

Creating & Editing C program

The first step is to create and edit the source program in C. the C program is usually written and edited in turbo C/C++ editor.

Saving C program

After writing or editing the source program, it is saved on the disk. The extension of the file must be “C”.

Compiling C program

In this step, the source program is compiled. The source program is converted into machine code. The C-compiler is used to translate the program source code into the machine code. After compiling source code, an object file with extension obj is created.

Linking C program

In this step, the linker object file to the required library files. After linking object code to the libraries, an executable file with extension exe is created.

Loading c program

In this step, the loader loads the executable file from disk into memory for execution. The program must be loaded into memory for execution.

Executing C Program

In this step, the program is executed on the computer. The cpu fetches instructions of program from memory one by one and takes action on them.

A diagram is show below which show the necessary steps that are taken to prepare a c program for execution.
