In this problem, we will use divide-and-conquer to write a program that computes the zeros of a given cubic equation. while a cubic formula exists, it is a proven fact that there is no formula that can solve every polynomial of degree 5, for example, and so it is important to consider numerical solutions like the one we will explore here that generalize to higher-degree polynomials. you may assume that the zeroes of these equations lie between -100 and 100 and that distinct zeroes differ by at least 0.01. your program should take as input four numbers, each on their own line, representing a, b, c, d (in that order) in the equation ax3 + bx2 + cx + d = 0.

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.
