When is a destructor called in C++?

Immediately after the constructor
Just before a program ends
When an object goes out of scope or is deleted
After a class function is executed

The correct answer is: When an object goes out of scope or is deleted

A destructor is a special function in C++ that is responsible for destroying an object's allocated resources before its memory is deallocated. It is called when an object goes out of scope or is explicitly deleted using the 'delete' keyword. Option A is incorrect because a destructor is not called immediately after the constructor, as constructors and destructors serve different purposes. Option B is also incorrect because a destructor can be called multiple times during a program's execution, not just before it ends. Option D is incorrect because a destructor is not called after a class function is executed, unless that function explicitly deletes the object.
