It keep showing these errors and I need help correcting the code above

Answer 1

Hello,

The program doesn't have any error that you specified. Only error which I got was as follows in the main.cpp
error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)
The error is corrected by including the header file #include <string> in main.cpp and I was able to execute and see the output given in screenshots.

Apart from these, there are not error found. But anyway I have identified the cause for the error based on your screenshots. If you still facing the issue, implement the below solutions:

Constructor and Getters

emp is instance of Class Employee and this class doesn't have methods getEmployeeNumber(), getAddr(), getHourlyWage() and getHoursWorked()

Solution: Replace the following methods with below given methods:

• getEmployeeNumber() with getENum()
• getAddr() with getAdd()
• getHourlyWage() with getWage()
• getHoursWorked() with getHours()

Setters

emp is instance of Class Employee and this class doesn't have methods setAddr(), setHourlyWage() and setHoursWorked()

Solution: Replace the following methods with below given methods

• setAddr("Braintree, MA") with setAdd("Braintree, MA")
• setHourlyWage(0.99) with setWage(0.99)
• setHoursWorked(5000.0) with setHours(5000.0)

calcPay

• calcPay() takes two aurgments both of type double. But as per the error message, no parameters are passed to this method
  Solution: Pass two parameters of type double to method calcPay(). Example calcPay(10.0, 20.0)
• emp is instance of Class Employee and this class doesn't have method setHoursWorked()
  Solution: Replace setHoursWorked(43.5) with setHours(43.5)

read() and write()

emp is instance of Class Employee and this class doesn't have methods getEmployeeNumber(), getAddr(), getHourlyWage(), getHoursWorked()

Solution: Replace the following methods with below given methods

• getEmployeeNumber() with getENum()
• getAddr() with getAdd()
• getHourlyWage() with getWage()
• getHoursWorked() with getHours()

Feel free to ask further doubts. Always here to clarify
