Explanation CALLBACK: In computer programming, a callback is executable code that is passed as an argument to other code. It allows a lower-level software layer to call a function defined in a higher-level layer. Usually, the higher-level code starts by calling a function within the lower-level code passing to it a pointer or handle to another function. While the lower-level function executes, it may call the passed-in function any number of times to perform some subtask. In another scenario, the lower-level function registers the passed-in function as a handler that is to be called asynchronously by the lower-level at a later time in reaction to something. A callback can be used as a simpler alternative to polymorphism and generic programming, in that the exact behavior of a function can be dynamically determined by passing different (yet compatible) function pointers or handles to the lower-level function. This can be a very powerful technique for code reuse.

- Manual Compiler Optimization:
- Help optimization is the process of using some optimization techniques that have been programmed into a compiler, to improve the performance or reach other objectives of the source code. These techniques callback definition.
- Manual Compiler Directive:
- Help is data embedded in source code by programmers to tell compilers some intention about compilation. A compiler directive often tells the compiler how to compile; other source code tells the compiler callback explain.
- Manual Constraint Satisfaction:
- Help intelligence and operations research, constraint satisfaction is the process finding a solution to a set of constraints. Such constraints express allowed values for variables, and a solution is callback what is.
- Manual CAAD: Computer Aided Architectural Design:
- Help Architectural Design (CAAD) software programs are the repository of accurate and comprehensive records of buildings and are used by architects and architectural companies. In a more general sense callback meaning.
- Manual Constraint Logic Programming:
- Help programming is a form of constraint programming, in which logic programming is extended to include concepts from constraint satisfaction. A constraint logic program is a logic program that contains callback abbreviation.
