const_cast

const_cast is a C++ casting operator that allows you to explicitly add or remove the const or volatile qualifier from a variable's type. This essentially enables you to modify an object that was initially declared as const or pass a const object to a function that expects a non-const argument. It's a powerful tool but should be used with caution, as modifying a truly const object directly can lead to undefined behavior.
