Template functions
One of the hallmarks of the C++ Standard Template Library (STL) is its commitment to type-generic programming. This allows algorithms to be written to operate on multiple data types, effectively sidestepping the restrictions of traditional type-specific functions. C++ achieves this remarkable feat using template functions. Let us explore these template functions.
A primer on function templates
At the heart of type-generic programming lies the function template, an incredible tool that allows developers to write functions without specifying the exact data types they will operate on. Instead of committing to a single type, templates let you define a blueprint, making the function adaptable to various types. Here’s a simple example: imagine writing a function that swaps the values of two variables. With function templates, this swap function can cater to integers, floats, strings, and even custom types!
