Explanation:
- Employee Class:
- The
Employeeclass stores information about an employee, including their name, hourly rate, and hours worked. - The
calculateSalarymethod computes the employee’s salary based on their hourly rate and hours worked. - The
displaymethod prints the employee’s details and calculated salary.
- The
- Add Employee (
addEmployee):- This function prompts the user to input an employee’s name, hourly rate, and hours worked.
- It creates a new
Employeeobject and adds it to theemployeesvector.
- Display Payroll (
displayPayroll):- This function iterates through the vector of employees and calls the
displaymethod for each one, showing their details and calculated salary.
- This function iterates through the vector of employees and calls the
- Main Function (
main):- The main function provides a simple text-based menu to interact with the payroll system.
- It uses a loop to continuously display the menu and process user choices until the user decides to exit.
- The menu options include adding an employee, displaying payroll information, and exiting the program.
Possible Enhancements:
- Data Persistence: Implement functionality to save employee data to a file and load it when the program starts.
- Input Validation: Add error checking and validation for user inputs to handle incorrect or invalid data.
- Advanced Payroll Calculations: Include support for overtime pay, deductions, and bonuses.
- User Interface: Develop a graphical user interface (GUI) using a library like Qt or SFML for a more user-friendly experience.
