Behavioral Design Patterns in C++ - Lexing and Parsing

The video tutorial explains the interpreter design pattern, focusing on creating a domain-specific language to evaluate boolean expressions. It covers lexical analysis, tokenization, and parsing to build a parse tree. Examples of expression evaluations are provided, demonstrating how the abstract syntax tree is constructed and evaluated to return boolean results.

What are the expected outputs of the expressions evaluated in the example?

Describe the process of evaluating an expression using an abstract syntax tree.
