Complete Modern C++ - Operator Overloading - Part V (Smart Pointer Basics)

The video tutorial covers memory management in programming, focusing on the creation and destruction of integer objects on the heap. It highlights the importance of calling 'delete' to prevent memory leaks and introduces the Resource Acquisition Is Initialization (RAII) idiom as a solution. The tutorial demonstrates implementing a smart pointer class that automatically manages memory, using operator overloading to mimic pointer behavior. The video concludes by mentioning standard library smart pointers for broader applications.

What is the primary reason for calling 'delete' on a pointer after its use?

• To increase program speed

• To prevent syntax errors

• To avoid memory leaks

• To enhance code readability

Which idiom is used to prevent memory leaks by binding resource lifetime to an object?

• Singleton Pattern

• Factory Method

• Resource Acquisition Is Initialization (RAII)

• Observer Pattern

What is the role of the 'destructor' in the 'intptr' class?

• To allocate memory

• To initialize variables

• To free allocated memory

• To print debug information

How does the 'intptr' class allow access to the member functions of the underlying resource?

• By using a global variable

• By implementing a callback function

• By overloading the arrow operator

• By using a static method

What is a smart pointer?

• A pointer that can change its type

• A pointer that automatically frees memory

• A pointer that can point to multiple objects

• A pointer that is faster than regular pointers

Which operator is overloaded to allow 'intptr' to be dereferenced like a pointer?

• The division operator (/)

• The asterisk operator (*)

• The minus operator (-)

• The plus operator (+)

What limitation does the custom smart pointer 'intptr' have?

• It is slower than regular pointers

• It requires manual memory management

• It cannot be used in loops

• It can only be used with integer objects
