Who Invokes the main function🤔🤔

Question

Who will invoke the main function in c or c++ or java. Can any one tell me please.

Answer 1

The operating system. Also, when you do "return 0" on the main function it tells the OS wether the program executed correctly. In linux, after executing a program from the terminal you can use "echo $?" to get the status of the previously runned program.
