Question

C++ question

The code below has five errors.  The errors may be syntax errors or logic errors, and there may be more than one per line; examine the code carefully to find them.  Indicate each of the errors you find by writing the line number and correction in the space provided below. You must find and correct all five of the errors.

If there were no errors, this code would output:

Paycheck for 123-45-678 : $690.625

Paycheck for 876-54-321 : $818.125

       anEmployee.printCheck();----------------------------------5
       secondEmployee->printCheck();
       delete secondEmployee;
       return 0;
       }

Explaination:

1. line no 8 i.e void printCheck() = 0; syntax is wrong method can't be intialized with 0. So after correction it is void printCheck();

2. line no 20 i.e Employee(),m_rate(rate),m_hours(hours){} syntax is wrong and also not passing any argument in parent class constructor i.e Employee().

So after correction it is m_rate(rate),m_hours(hours),Employee(theSSN){}

3. line no 24 i.e cout<<"Paycheck for "<< m_ssn << " : $" << getPay() << endl; here m_ssn is in private scope we can't access it directly by calling its name.

So after correction it is cout<<"Paycheck for "<< getSSN() << " : $" << getPay() << endl;

4. line no 34 i.e HourlyEmployee* secondEmployee = HourlyEmployee("876-54-321", anEmployee.getRate(), 38.5); syntax is wrong new keyword is missing.

So after correction it is HourlyEmployee* secondEmployee = new HourlyEmployee("876-54-321", anEmployee.getRate(), 38.5);

5. line no 35 i.e anEmployee->printCheck(); syntax is wrong anEmployee is an object it can access any function of a class using (.) operator only.

So after correction it is anEmployee.printCheck();
