The condition/expression is evaluated, and if the condition/expression is true, [1] the code within all of their following in the block is executed. This repeats until the condition/expression becomes false. Because the while loop checks the condition/expression before the block is executed, the control structure is often also known as a pre ...
Once this is done, everything is straightforward: the code continues by doing iterations of groups of eight instructions; this has become possible since the remaining number of iterations is a multiple of eight. [1] Duff's device provides a compact loop unrolling by using the case keyword both inside and outside the loop. This is unusual ...
Basic-256 started as a simple version of BASIC: the code editor, text output window and graphics display window are all visible in the same screen. [4] However, successive versions have added new features, [5] namely: Files (Eof, Size) – Version 9.4d; Mouse events – Version 9.4d; Sprites handling – Version 0.9.6n; Database functions ...
The message loop is an obligatory section of code in every program that uses a graphical user interface under Microsoft Windows. [1] Windows programs that have a GUI are event-driven. Windows maintains an individual message queue for each thread that has created a window. Usually only the first thread creates windows.
A conditional loop has the potential to become an infinite loop when nothing in the loop's body can affect the outcome of the loop's conditional statement. However, infinite loops can sometimes be used purposely, often with an exit from the loop built into the loop implementation for every computer language , but many share the same basic ...
Then the condition is evaluated. If the condition is true the code within the block is executed again. This repeats until the condition becomes false. 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.
(This can be partially mitigated if the original code and/or the copy are properly commented; however, even then the problem remains of making the same edits multiple times. Also, because code maintenance often omits updating the comments, [3] comments describing where to find remote pieces of code are notorious for going out-of-date.)
The Object Windows Library (OWL) is a C++ object-oriented application framework designed to simplify desktop application development for Windows and (some releases) OS/2. OWL was introduced by Borland in 1991 and eventually deprecated in 1997 in favor of their Visual Component Library (VCL).
