Behavioral Design Patterns in C++ - Pros and Cons-Visitor

The video tutorial explains the visitor pattern, a design pattern that allows adding new operations to an object structure without modifying its classes. It covers the classical and modern implementations, highlighting the advantages such as easy addition of new operations and localized features. However, it also discusses disadvantages like circular dependencies and potential encapsulation violations. The tutorial provides guidelines on when to use the visitor pattern, emphasizing its suitability for stable class hierarchies requiring new operations.
