Complete Modern C++ - Introduction to Templates

The video tutorial explains the concept of templates in programming, focusing on their use in generic programming to create functions and classes that can operate on any data type. It provides an example of a Max function to demonstrate how templates can simplify code by eliminating the need for multiple overloaded functions. The tutorial also covers the process of template instantiation during compilation, showing how the compiler generates specific functions based on the types used in function calls. The benefits of using templates, such as high performance and reusability, are highlighted, along with examples of libraries that utilize templates.

How does the compiler handle the instantiation of a function template?

In what scenarios would you need to use templates instead of writing separate functions for each data type?
