Problem Statement You are going to build a database that an employer can use to keep track of their employees. You will need a way to represent a single employee (name, id number, salary) and a way to store an unknown number of employees. You will build the capability to add remove employees from the database and provide some other functionality described below. Assignment Create an outlab5 project and paste this into a Driver. You won't need to change the Driver Here are descriptions of the methods you need o addEmployee. This method reads in name and salary to represent a new employee. The employee id number is just the number that employee was to join the company. I e. The first employee added has id number 1, the second id number 2 and so on. If an employee ends up leaving the company, employee numbers stay the same and new employees are still given the next number. E.g. If employee 1 leaves employee 2 stays employee 2 o remove Employee. This method removes an employee from the database based on the employee id number passed. I e. If employee 123 is to be removed, find the employee with id number 123 and remove them. If that employee does not exist, print an error message. o print Alphabetically. This method will print out all the employees in the database in alphabetical order. o printByld. This method will print out all the employees in the database by order of their id numbers starting with employee 1. If some employee (e.g. employee number 7) is no longer in the database, just skip that number. o pay Increase. Give each employee a pay increase of X% where X is the input parameter o getPayroll Cost. Return the total amount of salary of all the employees in the database Here is some sample output
