Question

class dateType Download source and header files of the class dateType from Blackboard. Rewrite the definitions of the function setDate and the constructor so that the values for the month, day, and year are checked before storing the date into the member vari- ables. If m, d and y denote day number, month number and year number, then If y s 0, then yis an invalid yearnumber. Change it to the default value of y- 1900 If m s 0 or me 2 13, then m is an invalid month number. Change it to the default value of m 1 If m s 0 or m 213, then m is an invalid month number. Change it to the default value of m>1 If m E {1,3,5,7,8, 10, 12): If d s 0 or d 2 32, then d is an invalid day number. Change it to the default value of d 1 If m E 14, 6, 9, 11 If d s 0 or d 2 31, then d is an invalid day number. Change it to the default value of d 1 If m 2: If y is a leap year number: If d s 0 or d 2 30, then d is an invalid day number. Change it to the default value of d 1
