Quiting Program error...

I'm trying to make a program that asks the user if they wish to quit. but Dev-C++ is giving me this error:

27 C:\Dev-Cpp\GradeBook.cpp no match for 'operator>>' in 'std::cin >> q'

here's the code:

Code:

---

#include <iostream>
#include <string>
using namespace std;
class GradeBook
{
public:
      void displayMessage()
      {
        cout << "Welcome to the Grade Book!" << endl;
      }
};

int main()
{
 top:
 system("CLS");

 GradeBook myGradeBook;
 myGradeBook.displayMessage();

 string q[1000000];
 q[0] = "y";
 do
 {
  topOfLoop:
  cout << "\nDo you wish to quit? (y/n): ";
  cin >> q;
  if (q[0] == "n") goto top;
  if (q[0] == "y") return 1;
  else
      cout << "That's not a choice!\n\n";
      goto topOfLoop;
 }
 while (q[0] != "y");
 
 return 0;
}

I recently changed the array to a string array from a char array. The char array worked a little better but I'm trying to improve the program. Any help?

If you want to use a string instead of a character array, just make q a string instead of a string[10000000]. Then refer to it as q instead of q[0].

A character array is used to represent a single string in C. In C++, you need only one instance of the string class.

Do youself a favour.
Get rid of the goto statment.

uh, that hurts my brain... how about char choice; cin >> choice; .....
