In addition to a guard attached to a pattern, pattern guard can refer to the use of pattern matching in the context of a guard. In effect, a match of the pattern is taken to mean pass. This meaning was introduced in a proposal for Haskell by Simon Peyton Jones titled A new view of guards in April 1997 and was used in the implementation of the ...
The original form of the pattern, appearing in Pattern Languages of Program Design 3, [2] has data races, depending on the memory model in use, and it is hard to get right. Some consider it to be an anti-pattern. [3] There are valid forms of the pattern, including the use of the volatile keyword in Java and explicit memory barriers in C++. [4]
In the mid-1950s, when assembly language programming was commonly used to write programs for digital computers, the use of macro instructions was initiated for two main purposes: to reduce the amount of program coding that had to be written by generating several assembly language statements from one macro instruction and to enforce program ...
Sample Code: An illustration of how the pattern can be used in a programming language. Known Uses: Examples of real usages of the pattern. Related Patterns: Other patterns that have some relationship with the pattern; discussion of the differences between the pattern and similar patterns.
This style of coding has the disadvantage that the subroutine returns from multiple (possibly many) points and some coding standards discourage having multiple return points. Another way to is to check each condition and if the condition succeeds, enter a deeper block of code that checks the next condition and so on. The deepest enclosing block ...
Parity in this form, applied across multiple parallel signals, is known as a transverse redundancy check. This can be combined with parity computed over multiple bits sent on a single signal, a longitudinal redundancy check. In a parallel bus, there is one longitudinal redundancy check bit per parallel signal.

While such acceptance is subjective, and often depends on individual coding habits, the following are common examples: the use of 0 and 1 as initial or incremental values in a for loop, such as for (int i = 0; i < max; i += 1) the use of 2 to check whether a number is even or odd, as in isEven = (x % 2 == 0), where % is the modulo operator
