This document discusses different loop control structures in C++ including while, do while, and for loops. It explains the differences between these loops and provides examples of how to use the continue and exit statements. The exit statement is used to terminate a program and return to the operating system, optionally returning an exit code to indicate success or error.

8. The exit statement
 The exit() function is used to terminate
program execution and to return to the
operating system.
 The return code "0" exits a program without
any error message, but other codes indicate
that the system can handle the error
messages.
Syntax
void exit(int return_code);
