Why won't C++ let me use a string as a data member in a class? -

so have following code in header file named classes.h:

#ifndef classess_h #define classess_h  class palindromecheck { private:     string strtocheck;     string copy;  public:     palindromecheck(string testsubject) : strtocheck(testsubject) {} //constructor      void check()     {         copy = strtocheck; //copy strtocheck copy once strtocheck has been reversed, has checked against.         reverse(strtocheck.begin(), strtocheck.end());  //reverse string can checked see if palindrome.          if (strtocheck == copy)          {             cout << "the string palindrome" << endl;             return;         }         else          {             cout << "the string not palindrome" << endl;             return;         }     } };  #endif 

and have following code in source file:

#include <iostream> #include <string> #include <algorithm> #include "classes.h" using namespace std;  int main() {     palindromecheck firstcheck("atoyota");      firstcheck.check();      return 0; } 

when compiled code using visual c++ compiler, got ton of errors messages stemmed these first four:

'strtocheck': unknown override specifier missing type specifier - int assumed. 'copy': unknown override specifier missing type specifier - int assumed.

i tried adding in #include <string> header file , recompiled did absolutely nothing. confuses me because thought use string datatype, apparently not in class? great if me out because don't know why code isn't working.

you need #include <string> in class header itself.

you need either use std:: namespace (preferable) or add using namespace std header (which discourage).
