As many of them have answered here, main is a special
function in C/C++ programs. The compiler does not care if
you have defined main or not, but linker does. If linker
finds main defined in the objects being linked, then the
address of main function is placed at the top of execution
stack. And automatically when loader loads the
program/process, the main function gets loaded at the top of
execution stack, and system starts execution using
__crtmain() which internally calls main() of the program/process
