How do we Run a C program in linux...

First create a file.c, obviously having a C code.

/* FILE: test.c */
#include <stdio.h>
void main()
{
    printf("Hi!!!!!!!!!");
}

Go to terminal.

We assume this file.c is on desktop.

Test the file with

cd Desktop

ls file.c

It will echo the filename if succeeded.

Now type

gcc -Wall file.c

On succes, it returns the command prompt.

like

sujit@sujit-desktop:~/Desktop$ ls test.c
test.c
sujit@sujit-desktop:~/Desktop$ gcc -Wall test.c
sujit@sujit-desktop:~/Desktop$

to run the file type

chmod +x a.out

the output will be displayed.

Here a.out is the executable file created, which runs the executable code of your program. In Windows .obj file is created. My observation is, linux creates .out file which is directly executable. This must be the difference in Windows[;(] and Linux[:)].
