What are constructors and destructors in C++?

What are constructors and destructors in C++?

Constructors are special member functions that initialize objects, while destructors clean up before an object is destroyed.

Can you give me an example of a constructor?

Sure! Here's a simple example:

class MyClass {
public:
    MyClass() { // Constructor
        // Initialization code
    }
};

What about destructors? How do they work?

Destructors are defined with a tilde (~) before the class name. They are called when an object goes out of scope:

class MyClass {
public:
    ~MyClass() { // Destructor
        // Cleanup code
    }
};

Are there any rules I should follow when using them?

Yes, ensure that constructors initialize all member variables, and destructors should release any resources allocated during the object's lifetime.
