"The revelation of C + + disassembly and reverse analysis technology"--the destructor

• Local objects

When the object's scope ends, the stack space is destroyed, at which time the destructor is called.

Example:

The destructor is called automatically when the function returns:

• Heap Object

Call the destructor function to handle the destructor:

Why use a destructor function to call a destructor ? Consider that if the object of the delete is an array of objects, you can use the destructor function to refactor all the objects in turn. Example:

The construct agent function was called:

In the vector deleting destructor function, the flag bit is judged first:

If there is no jump, indicating that the delete is an array, then the call to the destructor function is called to deconstruct the object one-by-another. If a jump is made, only one call to the destructor is made.
