You need to get the minutes from the user, but you want to limit the input to values between 0 and 60. Part of the loop condition that will be used to display an error message is written for you, but something is missing. Provide what is missing.

 cout << "Enter the minutes: "; cin >> minute; while(minute < 0__________minute > 60) { cout << "Invalid minute. Try again: "; cin >> minute; }
