Yes, that works.

string is in the std namespace so try std::string or add "using namespace std;" near the top of your file.
Okay, that works too, and it takes care of the "deprecated" warnings too when I was using the header files 'iostream.h' and 'fstream.h' (instead of the more current and correct 'iostream' and 'fstream').
I hadn't realized that there are new ANSI C++ standards for specifying
the inclusion of headers in your code (at least they are new to me!!).
Since I don't program all that much, this was the first trouble I had when I encountered them. I will have to read up on these to avoid
further difficulties in the future.
Many thanks for your help!
----- Despite the fact that the header file "string" is located in the directory /usr/include/c++/3.3.3 the compiler seemingly can't locate it. This is puzzling since it lists this path in the #include search path above. Even placing the source code into the /usr/include/c++/3.3.3 directory and trying to compile it there gives the same error. What am I overlooking here, or not understanding?
Why do you think it was not found, the compiler did not output any error messages indicating this.
I was assuming that it wasn't found based on the error messages
'euler.cpp:21: error: `string' undeclared (first use this function)
euler.cpp:21: error: (Each undeclared identifier is reported only once for each function it appears in.)'
that I was getting. However, with the directive you gave me (the "using" above), everything seems to have cleared up. Once again, I must read up on the new standards and their proper usage.
Thanks again!
