# Answer to Question #50781 in C++ for zexy

Question #50781
A. Create a DateException that descends from the built-in runtime_error exception
class. Include fields that hold a month, day, and year and include get functions for each of
the values.
B. Create a Date class. Data fields include month, day, and year. Include an exception function
that prompts for and accepts values for each of the data fields, and that throws a
DateException if the month is less than 1 or more than 12 and if the day is out of range
for the entered month. (Assume February can have 29 days.) Allow any value to be accepted
for the year. Also include an overloaded insertion operator to display a Date’s data values.
