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 happens if I don't define a destructor?

If you don't define a destructor, C++ provides a default one that handles basic cleanup. However, if your class allocates resources, you should define one to avoid memory leaks.

How do I call a constructor with parameters?

You can call a constructor with parameters by passing the arguments when creating an object, like this:

MyClass obj(5);
