When should I use destructors in C++?

When should I use destructors in C++?

Destructors are used in C++ to clean up resources when an object goes out of scope. You should use them when your class allocates resources like dynamic memory, file handles, or network connections.

Can you give me an example of a destructor in a class?

Sure! Here's a simple example:

class MyClass {
public:
    MyClass() { /* constructor code */ }
    ~MyClass() { /* cleanup code, e.g., delete allocated memory */ }
};

What happens if I don't use a destructor?

If you don't use a destructor, any resources allocated by your class may not be released properly, leading to memory leaks or other resource exhaustion issues.

Are there any cases where I shouldn't use a destructor?

Yes, if your class doesn't manage any resources or if it only contains members that automatically handle their own cleanup, you may not need a destructor.
