I'm trying to figure out how to get my changeSalary function to work as well as my listSalary, my professor told us to use the setRating function but this error keeps popping up

Yes the function Job::setRating(double) is missing. You need to ask your professor about it.
Maybe it's your task to write it.
Maybe it was just forgotten.

this is due at 11:30 tonight it might be a litte too late, do you have an idea on how to do that? I'm so lost on these last two functions and I'm having a big brainfart
