How do C++ objects on the heap get destroyed?

Automatically by the compiler
Using the delete keyword
By exiting the program
With garbage collection

The correct answer is: Using the delete keyword

Objects on the heap in C++ are created using the "new" keyword and are allocated dynamically, allowing for more control over memory management. However, because these objects are created manually, they must also be destroyed manually using the "delete" keyword. This frees up the memory allocated for the object and prevents memory leaks. Options A, C, and D are incorrect because objects on the heap are not automatically destroyed by the compiler, they are not destroyed by exiting the program, and C++ does not have a built-in garbage collector. Using the delete keyword is the proper and necessary way to destroy objects on the heap in C++.
