1. [3 points] Do Exercise # 16.15 on page 625 of the textbook "C How to Program." You must not have any public data members in your class. 2. 3 points) Add to your program, a class called Time 1960 that is used to track time of day in hours 0 to 23), minutes (0 to 59), and seconds (0 to 59). Use this class in your program and prompt the user to enter time of the day. Your program displays the entered time in the format HH:MM:SS (hours, minutes and seconds). You must not have any public data members in your class. 3. [4 points] Using the classes created in parts 1 and 2 (above), enhance your program to: a. Prompt the user for two date-time pairs (that is a date and time for the first pair and a date and time for the second pair). Display the two entered values in the format month/day/year HH:MM:SS. b. Display the total number of seconds between the two date-time values. need this program in C++ xercise 16.15: (Date Class) 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). Your class should have a constructor with three parameters that uses the parameters to initialize the three data members. For the purpose of this exercise, 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 set and a get function for each data member. Provide a member function displayDate that displays the month, day and year separated by forward slashes (1). Write a test program that
