C++ Cannot find Include

In main.cpp I keep getting errors saying that print was not defined (and other errors of the sort.

I have print() defined under a header file called "misc"

misc.h

#include <iostream>
#include <cstdlib>
#include <fstream>
#define MISC_H
#ifndef MISC_H

void print(string str) { cout << str << endl; }

string userIn(string prompt = "Option:") { //For collecting user responses
  string response;
  print(prompt);
  cin.clear();
  cin.sync();
  getline(cin, response);
  if (!cin) { response = "wtf"; }
  else if (response == "512") { //Secret termination code
    print("Program terminated");
    exit(0);
  }
  print("");
  return response;
}
#endif

Then in main.cpp I #include Headers/misc.h" (The header file is located in a separate folder)

Is there something I'm doing wrong here?
