In C++, templates are a powerful feature that allows you to define generic types and functions. Templates enable you to write code that can handle multiple data types without the need to rewrite the code for each specific type.
Template functions and classes are defined using parameterized types. These types are represented by placeholders called "template parameters". When the code is compiled, the template parameters are replaced with the actual types provided by the user, creating specialized versions of the code.
Template functions:
A template function is a function that can operate on different data types. It is defined using the template keyword followed by the template parameter list.
Template classes:
Similar to template functions, template classes allow you to define generic classes that can work with different data types. The template parameters are specified within angle brackets ＜＞ after the class name.
Template specialization:
Template specialization allows you to provide specific implementations for certain types. It allows you to customize the behavior of the template for specific case.
Templates provide a powerful way to write generic code that can be reused with different types. They allow for code flexibility, reduce code duplication, and improve code maintainability. Templates are extensively used in the C++ Standard Library to provide generic algorithms and containers.
