Write a program that prints the day number of the year, given the date in the form month-day-year. for example, if the input is 1-1-2006, the day number is 1; if the input is 12-25-2006, the day number is 359. the program should check for a leap year. a year is a leap year if it is divisible by 4, but not divisible by 100. for example, 1992 and 2008 are divisible by 4, but not by 100. a year that is divisible by 100 is a leap year if it is also divisible by 400. for example, 1600 and 2000 are divisible by 400. however, 1800 is not a leap year because 1800 is not divisible by 400.

Design a payroll class with the following fields: • name: a string containing the employee's name • idnumber: an int representing the employee's id number • rate: a double containing the employee's hourly pay rate • hours: an int representing the number of hours this employee has worked the class should also have the following methods: • constructor: takes the employee's name and id number as arguments • accessors: allow access to all of the fields of the payroll class • mutators: let the user assign values to the fields of the payroll class • grosspay: returns the employee's gross pay, which is calculated as the number of hours worked times the hourly pay rate. write another program that demonstrates the class by creating a payroll object, then asking the user to enter the data for an employee in the order: name, id number, rate, hours. the program should then print out a statement in the following format (for example, if you had an employee named chris jacobsen with id number 11111, who works for 5 hours at $10/hr): chris jacobsen, employee number 11111, made $50.00 in gross pay. using text forming so that the gross pay is rounded to two decimal places.
