I am trying to practice user validation, as in if I enter a letter instead of a number, I get a 0 for the output, can someone look at my code and tell me how to fix it

int number;
       do {
           std::cout << "enter number to be checked" << endl;
           cin >> number;
           if (number % 2 == 0)
           {
               std::cout << "perfect" << endl;
               break;
           }
           else
           {
               std::cout << "do not pass go, do not collect 200 dollars and try again" << endl;
               if (cin.fail())
                   cout << "Not a number " << endl;
               continue;

           }
           break;
           if (cin.fail())
               cout << "Not a number " << endl;
       } while (!cin.fail());
       cout << "number is " << number << endl;
