How does =delete on destructor prevent stack allocation?

Question

In this SO question is stated that this construct prevents stack allocation of instance.

class FS_Only {
    ~FS_Only() = delete;  // disallow stack allocati         


        

Answer 1

The only way to allocate such an object would be through dynamic allocation, without any de-alocation (the object will either be leaked, or accessed by pointer for the duration of the program.

Any attempt to allocate a static instance will cause a compilation error when the allocated object would go out of scope (as the destructor code cannot be called).
