Employees and Managers

A company pays every employee a salary. A manager is an employee too, but earns a bonus on top of the salary. Write the two classes so that a manager reuses everything an employee has, and changes only how its pay is worked out.

Implement the class Employee:

• Employee(name, salary) creates an employee. The name and the salary are private to Employee.
• pay() returns the salary.
• describe() returns the text <name> earns <pay>, where the amount is what pay() returns, for example Ana earns 3000.

and the class Manager, which inherits from Employee:

• Manager(name, salary, bonus) lets the parent's constructor store the name and the salary, and stores the bonus itself, private to Manager.
• pay() returns the parent's pay() plus the bonus. Call the parent's version, as in the lesson Calling the Parent Method: the salary is private to Employee, and the parent's pay() is what knows how an employee is paid.
• describe() is not written again: Manager inherits it unchanged. Because describe() calls pay(), a manager's description shows the manager's pay, bonus included.

The input is a list of people, one per line: employee name salary or manager name salary bonus. For each line, the code that tests your classes creates that object and prints what its describe() returns, on a line of its own. The starter code spells these names the way your language does.

Example 1:

Input:
    employee Ana 3000
    manager Bob 4000 1000
Output:
    Ana earns 3000
    Bob earns 5000
Explanation:
Ana's pay is her salary. Bob's pay is the parent's pay, his salary 4000, plus his bonus 1000.
Bob's describe() is Employee's describe(), but the pay() it calls is Manager's.

Example 2:

Input:
    manager Cleo 5000 0
    employee Dan 5000
Output:
    Cleo earns 5000
    Dan earns 5000
Explanation: A manager whose bonus is 0 earns exactly the salary, like an employee.

Example 3:

Input:
    manager Eve 7000 2500
    employee Finn 2800
    employee Gus 3100
    manager Hana 6000 500
Output:
    Eve earns 9500
    Finn earns 2800
    Gus earns 3100
    Hana earns 6500
Explanation: Employees and managers come in any order, and each object keeps its own name and numbers.

Constraints:

• 0 <= salary <= 106
• 0 <= bonus <= 106
• A name is one word of 1 to 20 English letters. Two people may have the same name.
• At most 100 people per test case.
