Structural Design Patterns in Modern C++ - Implementing String Interning

The video tutorial covers the implementation of constructors, including default, parameterized, copy, and move constructors. It explains string operations such as getting length and assigning values, and discusses the use of static count variables and stream operators. The main function demonstrates creating and modifying string instances, highlighting the Flyweight design pattern for efficient memory usage through string interning.

What is the significance of checking for NULL pointers in the get length and get string methods?

What modifications are necessary for the constructors and destructor of the string class to manage the count variable?

How does the implementation of the Flyweight design pattern affect memory consumption in string instances?
