Sometimes letting the compiler decide on the proper type is the best way to write your code. And sometimes you can set yourself up for surprises. Programming is not a good place for surprises.
This class will show you how to use the auto type properly in your code as well as how to get declared types with decltype:
- Why auto and decltype are needed.
- When to use them and when to avoid them.
- How to use auto by itself.
- How to use auto with iterators. Including how to get constant iterators.
- How to use auto with function pointers.
- How to use auto with const and with references.
- How to use decltype but itself.
- And how to use decltype together with auto.
This is an online class that you can attend from anywhere. All you need is a good internet connection and your computer. It will help if you have a large monitor or even two monitors so that you can watch and follow along at the same time. Headphones or earbuds with a microphone are recommended to avoid echos.
This is a live class where you can ask questions if you like. Or you can listen and learn and follow along without asking anything if that makes you more comfortable.
