        //      The case of a Switch statement cannot be of type Double. It can be any other type. The double specifically will mess up the compiler due to its use of decimal places. 

        //2. Can you have duplicate cases in a Switch?

        //      No, we can't have duplicate cases in a Switch statement. Similar to using doubles, it will cause an error with the compiler. The program will be unsure of what you're instructing in to do. 

        //3. Can you use a variable in the case? i.e., Instead of “case 0:” have “case x:”

        //      No, we can't use a variable in the case. It needs to be constant in order to be understood by C# operator.
