Bug how the operating system compiles c programs at the time of booting.
unix and linux does not makes executable files for all the programs.
it compiles it and executes it whenever require.
at the time of booting the system, how kernel compiles those c programs without "gcc".

Sorry, but you're quite mistaken. It does not compile executables on boot, it keeps executables on disk like anything else.

Having source code available doesn't mean you always need to use it. You just have the option, should you need it.
