We define constructors to simplify the process of initializing a class, whereas a destructor is a function that gets executed when an object's lifetime ends. Its main purpose is to free up any resources that the object acquired during its lifetime. The compiler provides default implementations for both the constructor and the destructor. However, these default implementations may not always satisfy our needs, as we just saw in our example. So let's declare a constructor for our review class in the review.h file.
