Templates in c. While the title of this article is a question it could also be made into a statement. In simple terms you can create a single function or a class to work with different data types using templates. This article is about when and why not to specialize templates.
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. A template is a blueprint or formula for creating a generic class or a function. Templates are powerful features of c which allows you to write generic programs.
This article appeared in cc users journal 197 july 2001. The only portable way of using templates at the moment is to implement them in header files by using inline functions. 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.
Templates whats the idea behind templates. And types in c not only interact with code by means of constructions and assignments. Templates are among the most powerful features of c but they are too often neglected misunderstood and misused.
But they are the most convenient portable solution. 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.
Templates are the foundation of generic programming which involves writing code in a way that is independent of any particular type. A tutorial and handbook. Header files are not the only portable solution.
Classes ii overloading operators classes essentially define new types to be used in c code. Why not specialize function templates.
