Does not name a type, C++ error?

Question

Error messages: Display::Display = Display does not name a type, Member declaration not found,Type 'std::string' could not be resolved, add a breakpoint

Display::~Display = Display does not name a type, Member declaration not found, add a breakpoint

I've looked at other "does not name type" question on stack but most of them were due to misplacing, example: "does not name a type" error

I don't really think I misplaced anything considering it's only 1 header file but maybe I overlooked something? Any help would be appreciated

display.h

#ifdef DISPLAY_H
#define DISPLAY_H

#include <string>

class Display{
          public:
                Display(int width, int hight, const std::string& title);
                virtual ~Display();
         protected:
         private:
                Display(const Display& other){}
                Display& operator = (const Display& other){}
       };
 #endif

display.cpp

#include "project\display.h"
#include <iostream>

Display::Display(int width, int hight, const std::string& title){}
Display::~Display(){}

please update the post and add the code instead of screenshots — ΦXocę 웃 Пepeúpa ツ, Apr 11 '17 at 04:32
that's all the code I have other than an empty main.cpp with a main function but I couldn't include that because I'm only limited to 2 links — user7839375, Apr 11 '17 at 04:34
@user7839375 They're saying that you should put the code in the question, not link to screenshots. — cdhowie, Apr 11 '17 at 04:34

Replace:

#ifdef DISPLAY_H
// ...
#endif

with:

#ifndef DISPLAY_H
// ...
#endif

Your compiler basically sees Display.h as an empty file, because DISPLAY_H is not defined, and #ifdef skips out the whole class declaration in the header file.
