230,688 PointsThe term "stub out" means to minimally implement the required elements for the code to compile but not necessary operate. From looking at how the class will be used, you can see that the "Calculator" class will need:
- a constructor that takes a double argument
- a public property named "Result"
- a method named "Add" that takes a double argument
And the error is caused by the declaration "var double
", only one of those words should be used at a time.
