With four kinds of loops, ranges, and even the infamous goto statement, there’s a lot more under the hood. Add to that the variety of collections – vectors, maps, stacks, and more – and each can require a different iteration technique. Some patterns are less efficient; others may introduce subtle, hard-to-detect bugs.

But iteration in C++ doesn’t stop with conventional loops. What happens when you need to iterate over a variadic parameter pack or a heterogeneous container like std::tuple? These situations require more advanced techniques, and standard patterns often fall short.

In this talk, we’ll explore the full spectrum of iteration in C++. From basic constructs to powerful metaprogramming idioms, we’ll revisit this fundamental concept with fresh eyes.
