What is the role of constructors and destructors in C++?

A constructor is a special member function used to initialize an object’s data members when creating the object. Its purpose is to initialize the object’s state, assign initial values to its data members, and ensure that the object is in an appropriate state when created.

A destructor is a special member function that is used to clean up the resources held by an object when it is destroyed. Its purpose is to free up the resources occupied by the object to prevent memory leaks and resource leaks, ensuring that the object can properly clean up its resources when it is destroyed.

In general, the constructor is responsible for initializing an object, while the destructor is responsible for cleaning up an object. Both ensure that the object is in the correct state when created and destroyed, guaranteeing the correctness and robustness of the program.
