Terminates the process normally, performing the regular cleanup for terminating programs.
Normal program termination performs the following (in the same order):
Note that objects with automatic storage are not destroyed by calling exit (C++).
If status is zero or EXIT_SUCCESS, a successful termination status is returned to the host environment.
If status is EXIT_FAILURE, an unsuccessful termination status is returned to the host environment.
Otherwise, the status returned depends on the system and library implementation.
For a similar function that does not perform the cleanup described above, see quick_exit.
If the program termination process described above throws an exception, terminate is automatically called.

Terminate calling process
Normal program termination performs the following (in the same order):
- Objects associated with the current thread with thread storage duration are destroyed (C++11 only).
- Objects with static storage duration are destroyed (C++) and functions registered with atexit are called.
- All C streams (open with functions in <cstdio>) are closed (and flushed, if buffered), and all files created with tmpfile are removed.
- Control is returned to the host environment.
Note that objects with automatic storage are not destroyed by calling exit (C++).
If status is zero or EXIT_SUCCESS, a successful termination status is returned to the host environment.
If status is EXIT_FAILURE, an unsuccessful termination status is returned to the host environment.
Otherwise, the status returned depends on the system and library implementation.
For a similar function that does not perform the cleanup described above, see quick_exit.
Parameters
- status
- Status code.
If this is0or EXIT_SUCCESS, it indicates success.
If it is EXIT_FAILURE, it indicates failure.
Return Value
none (the function never returns).Example

Data races
Calling this function destroys all objects with static duration: A program with multiple threads running shall not call exit (see quick_exit for a similar function that does not affect static objects).Exceptions (C++)
No-throw guarantee: this function never throws exceptions.If the program termination process described above throws an exception, terminate is automatically called.
