Please help me to create a automaticcaly executable file in c .when cpu boot up it should automatically execute once.
Thanks for the help

C files are not executable; you need to compile them to executable code.

Integrating with a boot process involves system-specific components. You have not provided any system details.

What exactly do you need this functionality for?

actually i am locking for an automatic executable file that runs on a system once for example a birthday program in c to fetch date from system automatically and display a " happy birthday" message on screen or consol . for this it should run on the system everytime once automatically when system boots up. thanks for the help
