how to compile .c extension file plz give me commands

You can compile it with the gcc command if you have installed the compiler package:

    gcc -o filename filename.c

if you have a simple C program, to compile it you have to use gcc. For example, to compile example.c type in terminal:

$ gcc example.c -o example.run

Further information with

$ man gcc

Btw, C programs normaly have a lot of modules and link to library. To compile everythings in a single shot you have to use "make" command.

$ man make

I suggest you to find a C programmer's guide with google cause is impossible to teach how to program in a support service like this.
