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]
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.
C++ also allows objects to provide an implementation of the function call operation. The Standard Template Library accepts these objects (called functors ) as parameters. Many dynamic languages , such as JavaScript , Lua , Python , Perl [ 1 ] [ 2 ] and PHP , allow a function object to be passed.
Many compound statements are loop commands or choice commands. In theory only one of each of these types of commands is required. In practice there are various special cases which occur quite often; these may make a program easier to understand, may make programming easier, and can often be implemented much more efficiently.
In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code executed once per ...
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.

In Microsoft Windows applications programming, OLE Automation (later renamed to simply Automation [1] [2]) is an inter-process communication mechanism created by Microsoft.It is based on a subset of Component Object Model (COM) that was intended for use by scripting languages – originally Visual Basic – but now is used by several languages on Windows.
