Inheritance Program Errors

[rebellion346]

Hey guys, I'm getting a few errors I can't seem to figure out solutions for:

(SalesEmployee Line 21) error C2248: 'SalariedEmployee::salary' : cannot access private member declared in class 'SalariedEmployee'

(SalesEmployee Line 17) error C2664: 'SalariedEmployee:: SalariedEmployee(const SalariedEmployee &)' : cannot convert parameter 1 from 'std::string' to 'const SalariedEmployee &'

I've been staring at it for a while now but I'm getting nothing unfortunately...

SalesEmployee Line 21) error C2248: 'SalariedEmployee::salary' : cannot access private member declared in class 'SalariedEmployee'

For this error:
make a getSalary() method int the SalariedEmployee class that returns the slaray as the private members are accessible only in the class they are declared so:
In the SalareidEmployee class do as follows:

   public double getSalary() 
   {
       return salary;
   }

And then use this method to access the value of salary in the SalesEmployee class:
Then in line 22 in SalesEmployee, instead of e.salary write e.getSalary()

SalesEmployee Line 17) error C2664: 'SalariedEmployee:: SalariedEmployee(const SalariedEmployee &)' : cannot convert parameter 1 from 'std::string' to 'const SalariedEmployee &'   

And for this error in line 18:
instead of SalariedEmployee(name) write the following: SalariedEmployee(name, sal)

I hope this would help
Cheers

I think you should make all those data members under the "protected" scope instead of "private", that would solve all your problems.

The string error is fixed thanks, but im getting an undeclared identifier error for the first solution

Thanks guys, I think it works now! :D
