Multi-Paradigm Programming with Modern C++ - Managing Memory

The video tutorial covers dynamic memory management in C and C++, focusing on the use of new and delete operators, and the RAII design pattern. It explains how smart pointers, particularly unique pointers, simplify memory management by automatically handling object deletion. The tutorial also discusses resource sharing, reference counting, and the benefits of using smart pointers over raw pointers. The video concludes with a preview of the next topic, shared pointers.

What is the primary purpose of using 'new' and 'delete' operators in C++?

• To handle dynamic memory allocation and deallocation

• To manage file input and output

• To perform arithmetic operations

• To manage network connections

What does RAII stand for in C++ programming?

• Resource Allocation Is Immediate

• Resource Allocation Is Initialization

• Resource Acquisition Is Initialization

• Resource Access Is Immediate

In the RAII pattern, when is a resource typically released?

• During the object's destruction

• When the program starts

• When the program ends

• During the object's construction

What is the main challenge in reference counting for shared resources?

• Decrementing the counter correctly

• Sharing the counter value among all instances

• Allocating memory for the counter

• Ensuring the counter is incremented correctly

What is a key advantage of using smart pointers over raw pointers?

• They automatically manage memory and prevent leaks

• They require less memory

• They are faster in execution

• They are easier to declare

Which smart pointer is known for taking ownership of an object and deleting it when it goes out of scope?

• shared_ptr

• weak_ptr

• unique_ptr

• auto_ptr

What function is commonly used to create a unique_ptr in C++?

• make_unique

• create_unique

• new_unique

• make_shared
