Restart A loop if Y/N

[BamMorrowXX]

using the bool continueYN what code and where do i need for the program to restart if 1 is pressed and to quit if 2 is pressed? Also if someone could look at the rand() I have and tell me why each loop generates the same number and how to correct it that would be great!

int main()

{
	srand(time(0));
	cout << "Cheapo Math Blaster" << endl;
	cout << endl;
	cout << "You gain one point per correct answer and one point is lost per wrong answer" << endl;
		cout << "If Your score falls to zero the game is over" << endl;
	int score = 1;
	int answer;
	int Attempt=3;
	int Number1;
	int Number2;
	Number1 = rand() % 20 ;
	Number2 = rand() % 30;
	bool continueYN = true;
	while (continueYN)
	{

		while (score > 0)
		{

			cout << Number1 << "+" << Number2 << endl;
			cin >> answer;
			{
				if (answer == Number1 + Number2)
				{
					cout << "Correct" << endl;
					score++;
					Attempt++;
					cout << "Score" << score << endl;
				}
				if (answer > Number1 + Number2)
				{
					cout << "Incorrect" << endl;
					score--;
					Attempt--;
					cout << "Score" << score << endl;
				}
				if (answer < Number1 + Number2)
				{
					cout << "Incorrect" << endl;
					score--;
					Attempt--;
					cout << "Score" << score << endl;
				}


			}
		}
		
	}
	



	
		system("Pause");
}
