Answer
The destructor for a class is called when the object of the class goes out of scope.
Solution
The destructor for a class is **called when the object of the class goes out of scope**. This means that once the object is no longer needed and is about to be destroyed—such as when a function ends or a block of code is exited—the destructor is automatically invoked to perform any necessary cleanup.
**Correct Option:**
- **when the object of the class goes out of scope.**
**Explanation of Other Options:**
1. **Only at the end of main:** This is incorrect because destructors are called whenever an object goes out of scope, not just at the end of the `main` function.
2. **Explicitly from the main program:** Destructors are typically called implicitly by the language runtime, not explicitly by the programmer.
3. **When the class is instantiated:** This describes the constructor, not the destructor. The constructor is called when an object is created.

The destructor for a class is automatically called when the object of that class goes out of scope, which typically happens at the end of a block of code or when a function returns. This ensures that any resources allocated by the object are properly released, helping to manage memory and prevent leaks—an essential part of good coding hygiene! For example, if you've created an object inside a function, as soon as you reach the end of that function, the destructor is triggered. This automatic cleanup is particularly useful in C++ for resource management, as it helps maintain efficiency and stability in your applications, especially when dealing with dynamically allocated memory.
