A C program may also use the exit() function specifying the integer status or exit macro as the first parameter. The return value from main is passed to the exit function, which for values zero, EXIT_SUCCESS or EXIT_FAILURE may translate it to "an implementation defined form" of successful termination or unsuccessful termination. [citation needed]
try {// Try to read the file "file.txt" Scanner sc = new Scanner (new File ("file.txt")); while (sc. hasNextLine ()) System. out. println (sc. readLine ()); sc. close ...
The exit operation typically performs clean-up operations within the process space before returning control back to the operating system. Some systems and programming languages allow user subroutines to be registered so that they are invoked at program termination before the process actually terminates for good.
I/O completion port loops run separately from the Message loop, and do not interact with the Message loop out of the box. The "heart" of most Win32 applications is the WinMain() function, which calls GetMessage() in a loop. GetMessage() blocks until a message, or "event", is received (with function PeekMessage() as a non-blocking alternative).
A loop invariant is an assertion which must be true before the first loop iteration and remain true after each iteration. This implies that when a loop terminates correctly, both the exit condition and the loop invariant are satisfied. Loop invariants are used to monitor specific properties of a loop during successive iterations.

Do while loops check the condition after the block of code is executed. This control structure can be known as a post-test loop. This means the do-while loop is an exit-condition loop. However a while loop will test the condition before the code within the block is executed.
An infinite loop is a sequence of instructions in a computer program which loops endlessly, either due to the loop having no terminating condition, [4] having one that can never be met, or one that causes the loop to start over.
