What are the best practices for using destructors in C++?

When using destructors in C++, it's important to ensure proper resource management. Always release resources like memory or file handles.

Should I always define a destructor for my classes?

Not necessarily. If your class doesn't manage resources, you can rely on the default destructor. However, if it does, you should define one.

What happens if I forget to define a destructor?

If you forget to define a destructor for a class that manages resources, it can lead to memory leaks or resource exhaustion.

Can you give an example of a class with a destructor?

Sure! Here's a simple example:

class MyClass {
public:
    MyClass() { /* allocate resources */ }
    ~MyClass() { /* release resources */ }
};
