How do destructors help in managing dynamic memory?

Can you explain how destructors work in C++?

Sure! Destructors are special member functions that are called when an object goes out of scope or is deleted. They help in cleaning up resources.

How do destructors manage dynamic memory?

Destructors can be used to free memory allocated with 'new'. When an object is destroyed, its destructor is called, allowing you to release any dynamic memory.

Can you give an example of a destructor in action?

Absolutely! Here's a simple example:

class MyClass {
public:
    MyClass() {
        data = new int[10]; // allocate memory
    }
    ~MyClass() {
        delete[] data; // free memory
    }
private:
    int* data;
};

In this example, the destructor ~MyClass() ensures that the memory allocated for data is released when an object of MyClass is destroyed.

What happens if I forget to use a destructor?

If you forget to use a destructor, it can lead to memory leaks, as the dynamically allocated memory will not be freed, causing your program to consume more memory over time.
