Templates in c. C s i p l s p l s see plus plus is a general purpose programming languageit has imperative object oriented and generic programming features while also providing facilities for low level memory manipulation. Why not specialize function templates. Classes ii overloading operators classes essentially define new types to be used in c code.
Templates are of great utility to programmers in c especially when combined with multiple inheritance and operator overloading. Templates are powerful features of c which allows you to write generic programs. But they are the most convenient portable solution.
This article appeared in cc users journal 197 july 2001. And types in c not only interact with code by means of constructions and assignments. Templates are a feature of the c programming language that allows functions and classes to operate with generic typesthis allows a function or class to work on many different data types without being rewritten for each one.
Quote from the c standard library. While the title of this article is a question it could also be made into a statement. Header files are not the only portable solution.
Templates function templates function templates are special functions that can operate with generic typesthis allows us to create a function template whose functionality can be adapted to more than one type or class without repeating the entire code for each type. The only portable way of using templates at the moment is to implement them in header files by using inline functions. Templates are the foundation of generic programming which involves writing code in a way that is independent of any particular type.
A template is a blueprint or formula for creating a generic class or a function. The complete guide provides software architects and engineers with a clear understanding of why when and how to use templates to build and maintain cleaner faster and smarter software more efficiently. It was designed with a bias toward system programming and embedded resource constrained and large systems with performance efficiency and flexibility of.
A template is a cookie cutter that specifies how to cut cookies that all look pretty much the same although the cookies can be made of various kinds of dough theyll all have the same basic shape. Templates whats the idea behind templates.
