Behavioral Design Patterns in C++ - Boolean Interpreter - III

The lecture discusses the implementation of design patterns by converting terminal and non-terminal expressions into classes, allowing easy modification and extension of grammar rules. It introduces the use of smart pointers to prevent memory leaks and demonstrates adding an OR expression to the interpreter. The lecture concludes with testing the new implementation and highlighting the flexibility of the interpreter pattern.
