Mastering C++ Standard Library Features [Video] - Passing Functions to Functions

The video explores higher order functions, which can take or return other functions. It covers techniques like function pointers, template parameters, and STD function, and introduces function ref, a lightweight type-erasing callable reference. Examples include using Lambdas for function arguments and returns, currying, and practical use cases like benchmarking. The video also discusses the pros and cons of each technique, emphasizing the flexibility and performance considerations of template parameters and STD function, and the potential of function ref for efficient, user-friendly function handling.

Explain the role of template parameters in implementing higher order functions.
