I'm getting this error when compiling using the suggested line for OS X.

Hi,

not an issue, just a possible contribution.

This tutorial is just awesome, and I wanted to have it on my e-reader. Since you mention this in README:

Generating more human-readable files from the tutorials (or the other way around?)

I made a small script to turn it into markdown, then epub, it's here: github.com/Gullumluvl/cpp_2_markdown.git

Sorry, that was not written in C++ though...!

best

P.S: the formatting is already so neat that making it a clean markdown was way too easy.

Hi,

I just finished chapter 3 and I noticed my IDE has greyed out the header - #include - suggesting that it isn't necessary. The program appears to run fine with or without it.

I can't see anywhere std::string is used in the program. Is it being used somewhere I haven't noticed and my IDE thinks it is unnecessary because the header is implicit in - #include - or is this really not needed?

If std::string is used, is it considered good practice to make headers explicit, rather than implicit in C++?

With the proliferation (if I think of a word that sounds more like how a disease spreads, I'll edit this) of unicode, it's become pretty common for new languages to make allowances for unicode strings, or to use unicode strings natively. In both cases, a character is a pretty strange type--and often we're talking about something that is 16 or 32 bits wide. This isn't the case in C++. I actually don't know off the top of my head what a character in C++ is (I think it's an 8-bit value representing... ascii?), so I think that (for experienced programmers, anyway) it might be good to mention that in passing.

Hi,
I wasn't able to exit program in chapter 6, i keep typing numbers in the terminal but where end of file?

if(std::cin.eof()) {
break;
}

when it breaks?
