Generic programming in C++ is a powerful feature that allows you to write flexible and reusable code. By using templates, you can create functions and classes that work with any data type, without having to rewrite the code for each type. This guide will walk you through the basics of implementing generic programming in C++, with a focus on template functions and classes.<\/p>\n
A template function is a function that can operate on different data types. You can define a template function by using the You can then call this function with any data type, as shown in the following example:<\/p>\n A template class is a class that can be used with different data types. You can define a template class by using the You can then create instances of this class with any data type, as shown in the following example:<\/p>\n Generic programming offers several benefits, including:<\/p>\n By using templates, you can write more efficient, reusable, and flexible code in C++.
