This guide delves into the nuances and pitfalls of undefined behavior in C++, focusing on variadic functions, the subscript operator in associative containers, and intricacies with iostreams. It highlights potential errors and undefined behavior scenarios that can occur with these features, providing practical examples and solutions. The chapter also touches on issues related to zero-sized types in structures and optimizing the size of data structures in C++.
