The exit function, declared in the standard include file <stdlib.h>, terminates a C++ program.
The value supplied as an argument to exit is returned to the operating system as the program's return code or exit code. By convention, a return code of zero means that the program completed successfully.
Note
You can use the constants EXIT_FAILURE and EXIT_SUCCESS, defined in <stdlib.h>, to indicate success or failure of your program.
Issuing a return statement from the main function is equivalent to calling the exit function with the return value as its argument.
For more information, see exit in the Run-Time Library Reference.
