The first (but not last) of the errors is here

                    it is like this:
.................................................. ...........
myDerivedClass(int a, int b) : myBaseClass(x, y) {} // line 4
.................................................. ............

                    it should be:
.................................................. ............
myDerivedClass(int a, int b) : myBaseClass(a,b) {} // line 4
.................................................. ...........

Good luck with the rest of the errors!
