EXIT_SUCCESS, EXIT_FAILURE

#define EXIT_SUCCESS /*implementation defined*/

#define EXIT_FAILURE /*implementation defined*/

The EXIT_SUCCESS and EXIT_FAILURE macros expand into integral expressions that can be used as arguments to the std::exit function (and, therefore, as the values to return from the main function), and indicate program execution status.

Notes

Both EXIT_SUCCESS and the value zero indicate successful program execution status (see std::exit), although it is not required that EXIT_SUCCESS equals zero.
