The below code is giving me an error. I'm cannot find the problem. I'm listing the code and the errors Xcode is giving me.
I'm trying to write the definition of the method in my class called "func()". I'm suppose to set the values of u and w to u = 10 and w = 15.3. Any ideas to what i'm doing wrong that is producing the following errors.

Not necessarily all of the functions, just the functions that you are actually using. The problem you are having is that you are trying to use a class where you defined the class constructors, but haven't implemented them.
