Re: Help !! With the error Posted..

line 2: unless you are using a very old compiler such as the original Turbo c++ you should be using header files without the .h extension because there have been some changes.

You should have named your derived string something other than String.h because that is already the name of standard C string functions. Its not good to duplicate file names like that because it will eventually become confusing.

My guess about your specific problem is that you did not include one or more required libraries in the project. Did you include the implementation code for your derived class ?
