In this part of my C++ tutorial I’ll start covering Regular Expressions. There are tons of examples and a problem for you to solve. I’ll cover how to search and then cycle through matches. We’ll look into cycling through matches with an iterator. Then we’ll create numerous regular expressions to get just that exact data we need and output or replace it.
All of the heavily commented code follows the video below. Feel free to do what ever you’d like with it. Continue reading C++ Tutorial 19
In this tutorial I’ll cover the Associative Containers, Set, Multiset, Map, and Multimap. I’ll also cover the Container Adapters : Stacks, Queues, and Priority Queues. And, finally we’ll explore enums.
