I am looking for the code for the c++ string class. What header is it implemented in?

A:
There is no single implementation for std::string. But you can find your particular implementation in the <string> header.
On my system it can be found here:
/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.0/include/g++-v4/bits/basic_string.h and /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.0/include/g++-v4/bits/basic_string.tcc
Generally, you are going to be looking for the basic_string template, since std::string is just a specialization of that.

Thank you. It appears only the prototype of the method I was looking for: find() is in there "size_type find(const _CharT* __s, size_type __pos, size_type __n) const;"

ahhh sorry. I've found it in basic_string.tcc. Thanks!

A:
As you might expect,
<string>
which will most likely be located in whatever include directory your compiler has as its base.

you are of course right, but keep in mind that (IIRC) `<string>` doesn't actually have to be an actual file. I never seen an implementation where it wasn't though...

It isn't a file on VMS; header files are contained in 'text libraries', whatever they are. Why, I've no idea.

A:
It's in <string>. It's a header file distributed with your compiler. It may include other (private) header files - a lot of the implementation for Visual Studio is in a file named "xstring".
