Need help adding a Yes continue/No end program loop

[hjabba89]

I don't know how/what/where to add a loop to continue if you type Y or end the program if you type N to the first question in my code.

  #include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;

int main()
{
	int randNumber;
	int userNumber;
	int answer;

	char again = 'Y';
	bool win = false;
	unsigned seed = time(0);

		srand(seed);
		randNumber = 0 + rand() % 501;

		cout << "I'm thinking of a number between 0 and 501. Do you want to guess what it is? (Y/N)" <<endl;
		cin >> userNumber;

		{
			while (!win)
			{				
				if (userNumber < randNumber)
				{
					cout << "Sorry, bud. You're number was out of range. You guessed too low, try again." << endl;
					cin >> userNumber;
				}
				else if (userNumber > randNumber)
				{
					cout << "Sorry, bud. You're number was out of range. You guess too high, try again." << endl;
					cin >> userNumber;
					cin.ignore();
				}
				else //winner
				{
					cout << "Yup, that was my number! We're done, you can leave now." << endl;
					win = true;
				}
			}



			

		}
		
cin.get();
return 0;
}

I'm assuming it goes on line 21, but I don't know what to put there.
