/*
 * Programmer: Dan Hopp
 * Date: 20-NOV-2019
 * Description:
    •	Create an array called salaryArray to store the hourly salary of 8 
        employees. Use the Math.random() method to randomly assign the hourly 
        salary to each employee. The salary should be in the range of $12.00 to 
        $75.00, inclusive. 
    •	Print contents of the salaryArray.
    •	Change the hourly salary to $55.00 for the employee with ID 5. 
    •	Print the salary and employee ID of the employee with the highest hourly
        salary.
    •	Print the salary and employee ID of the employee with the lowest hourly 
        salary.
    •	Print the difference between the highest and lowest hourly salaries.
    •	Assume that the national average for an hourly salary is $22.00. Print 
        the number of employees with an hourly salary higher than the national 
        average.
