What are constructors and destructors in C++?

Can you explain what constructors and destructors are in C++?

Sure! Constructors are special member functions that are called when an object is created, initializing its properties. Destructors, on the other hand, are called when an object is destroyed, allowing for cleanup.

How do I define a constructor in my class?

You define a constructor by creating a function with the same name as the class and no return type. For example:

class MyClass {
public:
    MyClass() {
        // constructor code here
    }
};

What about destructors? How do I define one?

A destructor is defined similarly, but with a tilde (~) before the class name. Here's an example:

class MyClass {
public:
    ~MyClass() {
        // cleanup code here
    }
};

Can you give me an example of when to use a destructor?

Certainly! Use a destructor when your class allocates resources like memory or file handles that need to be released when the object is no longer needed.
