well, first off I'm following a book that might be pretty old, so explain how I should correct anything thats out of date please, but the main problem I'm having is "apstring.h" the book says it just introduces a string, is there another #include file I can use to allow strings? (sorry im not sure what to enclose this in to get the code thing) #include <iostream> #include <conio.h> #include "apstring.h" int main() { apstring Name1 = "Suzie"; apstring Name2 = "Seymour"; clrscr(); std::cout << "Name1 = " << Name1 << std::endl; std::cout << "Name2 = " << Name2 << std::endl; getch(); return 0; } the error i get says cannot get the #include file "apstring.h"

Yes. First, trash your book. If you were doing the AP exam, it's in Java now. So it wouldn't help anyway. And if you truly wanted to learn modern C++, the book is useless anyway. Get a significantly better one like C++ Primer by Lippman and Accelerated C++ by Koenig.

There is a C++ string class, a good, standardised one. Look up C++ string on Google. Just type in "C++ string" on google. Google, aside from finding you answers to question like why the sky is blue, will also answer your programming questions ;p.

Oh, and don't rely on conio.h . Please, don't ever.

Just so you're clear as to what's going wrong with your program...when you specify a file to be included via the #include directive, your compiler needs to be able to find this file. Usually this is done one of two ways:

-Having the file in the same folder as the rest of your source code files
-Telling the compiler a directory where it should look for header filers

Now apstring.h, being a header file that was formerly produced and distributed by the college board for AP exams, is not a file that comes standard with any compilers. This means you would have to find it and download it, and then make sure the compiler can access it through one of the two methods mentioned above.

However I advise that you simply stick with the string class found in the C++ Standard Library. You'll be able to access it with any C++ compiler, and it's just as full-featured as the apstring class.

yes, you need to #include <string>
Like this:
#include <iostream>#include <string>int main(){std::string word;std::cin >> word;std::cout << "You have entered " << word << std::endl;return 0;}

I can't replace clrscr() because there is no standard way to clear the console window in C++, as such I would recommend just not even bothering.
