How vikasachar27-jpg/employee_payroll_system works
This is a console-based employee payroll application. A user enters employee details and selects operations in PayrollApp; the app creates full-time or part-time employees and delegates employee management and payroll generation to PayrollService. The service stores employees, lists or searches them, and calculates payroll by calling each employee’s polymorphic salary method. The model provides shared employee/person data, departments, and the Payable contract. README documents the full-time salary formula; sampled source also shows the part-time calculation. The graph reflects the inspected runtime code.
