In C and C++, constructs such as pointer type conversion and union — C++ adds reference type conversion and reinterpret_cast to this list — are provided in order to permit many kinds of type punning, although some kinds are not actually supported by the standard language.
They are implemented as a group of macro constants in the C standard library in the iso646.h header. The tokens were created by Bjarne Stroustrup for the pre-standard C++ language [1] and were added to the C standard in a 1995 amendment to the C90 standard via library to avoid the breakage of existing code.
You aren't gonna need it" [1] [2] (YAGNI) [3] is a principle which arose from extreme programming (XP) that states a programmer should not add functionality until deemed necessary. [4] Other forms of the phrase include "You aren't going to need it" (YAGTNI) [ 5 ] [ 6 ] and "You ain't gonna need it".

The Underhanded C Contest was a programming contest to turn out code that is malicious, but passes a rigorous inspection, and looks like an honest mistake even if discovered. The contest rules define a task, and a malicious component. Entries must perform the task in a malicious manner as defined by the contest, and hide the malice.
Pascal, a general-purpose programming language, which tended to be targeted toward use in schools as an introductory class to teach programming as an alternative to BASIC. Pascal became commonly used for hobbyist programmers in the 1970s and 1980s due to them being part of an integrated development environment allowing a person to edit, compile ...
In computer programming, redundant code is source code or compiled code in a computer program that is unnecessary, such as: recomputing a value that has previously been calculated [1] and is still available, code that is never executed (known as unreachable code),
