Consider that a system has two entities, Employee and Department. The employee has the following properties: employee name, number, SSN and salary. Similarly, the department has the following properties: department name, department number and a set of employees who are working on that department.
Implement the above system taking into account the following requirements:
1. In department, the number of employees that are working on this department is decided at the time when instantiating the department.
2. Assume that emp1 and emp2 are two objects of type Employee, write a code that enables you to write: if (emp1.isequal (emp2)). Where emp1, emp2 are employee objects. The statement is true if the objects have the same salary.
3. In department, make sure no two employees have the same employee number.
4. In department, write a method to increase the salary of an employee by a specific value. it should validate that value.
5. Write a getEmpByEno method in class department that returns a pointer to one of the employees in that department using the Employee number.
6. Write a getEmpByName method in class department that returns a list of employees in that department who have the same name.
7. Write a method to find the maximum salary in the department.
8. Write a code that enables you to write: if (equal (dept1, dept2)). Where dept1 & dept2 are departments object. The statement is true if the two departments have the same sum of employee salaries.
