Behavioral Design Patterns in C++ - Introduction-Iterator

The video tutorial explains the iterator design pattern, which allows sequential access to elements in an aggregate without exposing its underlying structure. It highlights the challenges of aggregates managing traversal and the benefits of using iterators, such as flexibility and a uniform interface. The structure of the pattern is detailed, including base and concrete iterators. Different types of iterators, internal and external, are discussed, along with their implementation in C, including advanced features like memory management and polymorphism.
