How to make a *.c file into a executive file?

[Sandeep M. Yelwatkar]

ok, here is a simple and short program which you can try, and learn.

create a file "try.c" using any editor with following contents
.
#include <stdio.h>
main()
{
    printf("Hello World\n");
}

save it and execute the following commands.

$ gcc try.c

This will produce an executable file a.out in the same directory.
then execute the command
$ a.out
To see the following printed on the terminal.
Hello World
$
In case a.out command fails, you probably need to try the following
command.
$./a.out

ok
Regards.
