Behavioral Design Patterns in C++ - Boolean Evaluator

The lecture covers implementing a lexer and parser without using the interpreter design pattern. It starts with setting up a project and creating two functions: one for the lexer and another for the parser. The lexer uses C++ string streams to tokenize input, while the parser evaluates boolean expressions. The lecture concludes by discussing the limitations of the current implementation and suggests refactoring using the Interpreter Design Pattern for better flexibility and maintainability.
