generic programming c++

First of all, I use the term templates and generic programming, whatever fits best. Generic programming in C++. In short there are three ways in which we can use templates in C++. C++ introduces with object-orientation and generic programming a new kind of abstraction. A template is a blueprint or formula for creating a generic class or a function. C++ adds greater typing strength, scoping, and other tools useful in object-oriented programming, and permits generic programming via templates. The _Generic(...) expression form is new in C11. The language C++ cannot be thought of as a mere extension to the C language. $ clang generic.c $ ./a.out Type of x is: string The new expression in this program is _Generic(x, char*: "string", int: "int"), which we see evaluates to "string". Generic programming is style of programming that is typeless, as in the type of data to be used is not determined at the time the code was written. Templates give the compiler a framework to generate code for the types it gets implemented with. In this post, I show how to do it in plain old C. We use the classic stack implementation. “_Generic”. Before I will only write about functional programming I will sketch the ideas of object-oriented, generic, and functional programming. This is stack.h: I know of two ways to perform generic programming in C. One way is to use pointer typecasting. Therefore we avoid to use Macro. The C++ programming language was devised by Bjarne Stroustrup as an approach to providing object-oriented functionality with a C-like syntax. First, we implement an int version. With a class, C++ … In Modern C++ Design, Andrei Alexandrescu opens new vistas for C++ programmers.Displaying extraordinary creativity and programming virtuosity, Alexandrescu offers a cutting-edge approach to design that unites design patterns, generic programming, and C++, enabling programmers to achieve expressive, flexible, and highly reusable code. In languages like Java and C++, it can be done easily. So, let us start with one of the most anticipated chapters in C++. Generic programming refers to the programming model where algorithms and functions are written in terms of ‘types’ so that it works on all data types and not just for one. In C++, class and function templates are particularly effective mechanisms for generic programming because they make the generalization possible without sacrificing efficiency. To make generic functions, using template functions; To make generic classes, using template classes We can define MACRO for the different types of data types. For example, the following macro INC(x) translates to INCl(x), INC(x) or INCf(x) depending on the type of x: Generic programming is an important idea in programming. Templates are the foundation of generic programming, which involves writing code in a way that is independent of any particular type. This book gives an overview of how C++ fits into the generic programming paradigm, and the author does a decent job of explaining how this is done. But after the implementation of C11 standard in C programming, we can use Macro with the help of a new keyword i.e. Object-oriented programming Generic programming is from my point of view the outstanding feature and the future of C++. The generic programming with templates. Hence it follows, that this and the upcoming posts are about the future of C++. In C you think in procedures and structures. In C++ this is achieved with templating. It supports object-oriented programming, and even more importantly, the generic programming paradigm. C++ implements generic programming concepts through templates. With C++11 we got the functional programming style. Generic programming is about generalizing software components so that they can be easily reused in a wide variety of situations.
