Hi, I'm using Bjarne's book to learn C++ and am stuck on the Calc program in Section 6. Everything works fine except when I try to use istringstream to parse a token from the command line. I thought I followed his instructions on page 118 correctly, but I can't get it to compile without syntax errors in the get_token() function. The whole program follows with the four syntax errors flagged with the text "// SYNTAX ERROR". Thanks in...

Is it possible to bind a switch statement to an Enum such that a compile-time error is raised if not all values within the Enum are handled in the switch statement? I realise you can use default: to catch unhandled cases, but of course this is only at run-time. Example: public enum MyEnum { one, two, three, four }
