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

The video tutorial explains the implementation of the interpreter design pattern. It covers the creation of terminal and non-terminal expression classes, which inherit from a common base class. The tutorial also discusses the need for a lexer and parser, and how to implement them. The parser class is modified to use expression pointers, and the parse function is adjusted to accept expressions directly. The video concludes with a brief overview of the changes made to the parser class and function.
