In the C and C++ programming languages, an inline function is one qualified with the keyword inline; this serves two purposes: . It serves as a compiler directive that suggests (but does not require) that the compiler substitute the body of the function inline by performing inline expansion, i.e. by inserting the function code at the address of each function call, thereby saving the overhead ...
Self-modification can be accomplished in a variety of ways depending upon the programming language and its support for pointers and/or access to dynamic compiler or interpreter 'engines': overlay of existing instructions (or parts of instructions such as opcode, register, flags or addresses) or
In the C programming language, an escape sequence is specially delimited text in a character or string literal that represents one or more other characters to the compiler. It allows a programmer to specify characters that are otherwise difficult or impossible to specify in a literal. An escape sequence starts with a backslash ( \) called the ...
Purge is a function that is sometimes necessary to use to update a wiki page whenever template- or subpage- transclusions are involved. Purging clears the page's server cache, and the page is rebuilt. Before purging, you may want to try first to refresh the page using your web browser . For updating a page display, any purge methods do the job ...
To use borax, follow these steps: Put on safety gloves. Make a solution of 1/2 teaspoon (tsp) borax, 8 tsp sugar, and 1 cup warm water. Stir until the sugar and borax are dissolved. Saturate ...
Peephole optimization is an optimization technique performed on a small set of compiler -generated instructions, known as a peephole or window, [1] that involves replacing the instructions with a logically equivalent set that has better performance. For example: The term peephole optimization was introduced by William Marshall McKeeman in 1965.
Loop unrolling. Loop unrolling, also known as loop unwinding, is a loop transformation technique that attempts to optimize a program's execution speed at the expense of its binary size, which is an approach known as space–time tradeoff. The transformation can be undertaken manually by the programmer or by an optimizing compiler.
In computer science, a pointer is an object in many programming languages that stores a memory address. This can be that of another value located in computer memory, or in some cases, that of memory-mapped computer hardware. A pointer references a location in memory, and obtaining the value stored at that location is known as dereferencing the ...
