Don't tell me in this case, cheapness doesn't pay. I downloaded Gaddis 6th edition for free, it has nothing of this kind at all. Wow, maybe I should pay some money and get a newer version. Now I have to guess reading codes!

Not just loop range based or the if else statement explained before. Don't they have a general name for this kind of simplified code. I just want to find a website that show the translation. I don't even know the name. I hate to ask every time I encounter this kind of simplified code. I am sure I can learn it just like that if I can have a table of translation.

Thanks

Gaddis's 6th ed. is copyrighted 2009, before the changes in C++. As John Arbuckle once said, "You get what you pay for." (Catch phrase used in ads for Yuban coffee)

Not sure which simplified code you're asking about. Do you mean the braced initializer list (e.g.,
T result{ data[0] }; ) ?

New features? C++ is a constantly evolving language, any book will become out of date.

I mostly use cppreference.com. As you can see there are new features introduced in c++20 (for example the spaceship operator), and there will be more coming in c++23.

Hi

I have been working on new stuffs using the book by Ivor, things that I never learned because the Gaddis I use is too old. So I have to take a detour to learn those. I think I cover the function templates quite well at this point. I just want to verify with you guys on my notes I have on typeid(), auto, decltype() and Trailing return type.

I find I like GeekForGeeks the best. It's the easiest to understand.

I attached my notes, I hope I am correct, if not, please let me know.

Thanks
