std_variant

dynamic typing

C++ is a statically typed language, meaning variable types are checked at compile time, but you can simulate dynamic typing (storing different types in the same variable at runtime) using std::variant (introduced in C++17)

A variant is a data type introduced in C++ 17 that can hold values of different types, much like a union in C. At its core, std::variant is a union of types. It can store one value at a time from a predefined set of types. Unlike a traditional union, std::variant keeps track of its active type, ensuring that you access the correct value.
