Class Destructors

A destructor in C++ is a special member function that is automatically called when an object goes out of scope or is explicitly deleted. Destructors are primarily used to clean up resources, such as releasing memory that was allocated with the keyword new.

To create a destructor, it's very similar to making a constructor, with one key difference: you need to add a ~ (tilde) in front of the class name. For example, if your class is named Foo, the constructor would be Foo() { ... }, and the destructor would be ~Foo() { ... }.

In this example, we’ll use a FileHandler class to simulate managing a file's lifecycle.
