Any input on how I can get firstDiastolic, secondDiastolic, thirdDiastolic, firstSystolic, secondSystolic, thirdSystolic to accept only positive integers? I am trying to use a while loop but am having trouble with implementing this with conditions on six variables.Code:void BP::GetPressure() { cout << "Please enter your Diastolic Pressure readings: "; cin >> firstDiastolic >> secondDiastolic >> thirdDiastolic; cout << "Please enter your Systolic Pressure readings: "; cin >> firstSystolic >> secondSystolic >> thirdSystolic; }
