Real-World Examples of Metaprogramming I
Discover how to apply metaprogramming techniques in C++ to implement a generic safe cast function. Learn to use constexpr conditions, static assertions, and type traits for compile-time verification of casts, ensuring safer and efficient code.

Advanced metaprogramming can appear very academic, so to demonstrate its usefulness, let’s look at some examples that demonstrate the syntax of metaprogramming and how it can be used in practice.
Example 1: creating a generic safe cast function
When casting between data types in C++, there is a multitude of different ways things can go wrong:
-
We might lose a value if casting to an integer type of a lower ...
