C++ problem 11-2
In this chapter, the class dateType was designed to implementthe date in a program, but the member function setDate and theconstructor do not check whether the date is valid before storingthe date in the member variables. Rewrite the definitions of thefunction setDate and the constructor so that the values for themonth, day, and year are checked before storing the date into themember variables. Add a member function, isLeapYear, to checkwhether a year is a leap year. Moreover, write a test program totest your class.
Input should be format month day year with each separated by aspace.
