Functional programming +is a programming paradigm in which functions are treated as regular values. +Thus, we can have functions that take other functions as parameters. The +former functions are called "higher-order" functions. A common feature of +functions is that they can be polymorphic. "Polymorphic" means that the same +function can be used with arguments of many types. FC++ is distinguished from +other libraries (including the C++ Standard Library) by its complete support +for polymorphism: FC++ polymorphic higher-order functions can take other +polymorphic functions as arguments and return polymorphic functions as results. +This is particularly useful (i.e., simplifies code) in C++ where type inference +is limited and we often need to pass polymorphic functions around and determine +their type later. + +With FC++ you can define your own higher-order polymorphic functions, but the +library also contains a large amount of functionality that can be re-used as-is +in C++ programs. This includes infinite ("lazy") lists, useful higher-order +functions (like map, compose, etc.), a reference-counting facility that can be +used to replace C++ pointers, many common logical and arithmetic operators in +a form that can be used with higher-order functions, and more. + +WWW: http://www.cc.gatech.edu/~yannis/fc++/ |
