title: Problem with Class for processing of strings
body: <p>I read lines from a text file and would like to repeated delimiters as \t\t. Normally I have between delimiters a parameter but for readability reasons it is sometimes nice to use strings as \t\t\t in order to line out text sequences.</p>
  
  <p>I wrote a class in my main.cpp that worked well. Because I would like to keep my main.cpp as compact possible, I tried to create a class file with header file. I did the forward declaration in the header file, and pasted the working class member in the class.cpp file.</p>
  
  <p>The Class uses string type variables that are declared in the class.cpp. When compiling the compiler gives me an error saying that "string does not name a type". I guess there is something wrong with the moment I do the include of the string.h header.</p>
  
  <p>It is included in the Main.cpp file. Should I include it also in the header file for the class or in the class.cpp file. I understood from previous exchanges that including libraries everywhere should be avoided.</p>
  
  <p>Thanks in advance,</p>
