Do this for month 2. You will find your mistake by looking at it. You havent give any value to "if" condition to compare.

else if (month == 2)
    {
        
            if ((year % 4==0 && year % 100 !=0)|| year % 400==0)
            {
                    cout << "Leap";
                    cout << " 29 days";
            }
            else
            {
                cout << "Common";
                cout << "28 days";
            }
