Question

Write the class definition for a class named Employee. The class should
include data members for an employee object's name and salary (the salary will
be an integer). The class should contain two member functions: the constructor
and a function that allows a program to assign values to the data members. Add
two member functions to the employee class. One member function should allow any
program using an employee object to view the contents of the salary data member.
The other member function should allow the program to view the contents of the
employee name data member. (Hint: have the member functions simply return the
contents of the appropriate data member).

Add another member function to the class. This function should calculate an
employee object's new salary, based on a raise percentage, provided by the
program (main function). Before calculating the raise, the member function
should verify that the raise percentage is greater or equal to zero. If the
raise percentage is less then zero, the member function should display an error
message.

Write main function that will create an array of employee objects, assign
values to the objects, display the names and current salaries for all objects,
ask user for the raise percentage and then calculate and display new salaries
for all objects.

Do this in C++
