Detailed Explanation
Answer: Deleting the same dynamically allocated object twice
A double delete can occur when a program attempts to release the same dynamically allocated object more than once.
For example, executing delete p; and then attempting to execute delete p; again without making the pointer safe can result in undefined behavior.
Modern C++ smart pointers and proper ownership design can greatly reduce this type of error.
