Create a class called date that
includes three pieces of information as data members—a month (type int), a day (type int) and a year (type int).
have a constructor with three parameters to initialize the three data members. call setters inside to initialize each attribute.
provide a set and a get method for each data member. assume that the values provided for the year and day are correct, but ensure that the month value is in the range 1–12; if it isn’t, set the month to 1.
provide a member function displaydate that displays the month, day and year separated by forward slashes (/).
