First of all you have to install linux in your computer.

HOW TO RUN C PROGRAM IN LINUX
1). Write and save the programOpen a simple text editor (e.g gedit), IDE (Eclipse) or command line code editor (Nano or Vim). I’ll be using gedit as it is very simple to use and it’s recommended for beginner programmers. Right Click on Desktop or any directory (Browse File using Nautilus) and select create new File – hello.c (.c extension is used to indicate that it’s a c program). Then write a simple program like this (and save the program press Ctrl+S)
#include<stdio.h>
main()
{
printf("Hello World\n");
/* Do something more if you want */
}
2)Compile the programGCC (GNU Compiler Collection) is installed by default, in Ubuntu. To compile the program, open the terminal and move on to the target directory type the command – (where gcc implies compiler name, then it asks for the file name of the source program while -o option specifies the file name of the output program)
gcc hello.c -o hello1
If there is no syntax/semantic error in you program then the compiler will successfully generate an executable file, otherwise fix the problem in your code.
3)Type the command
./hello
This should result in the output
Hello world
