I'm having some difficulties understanding how functions work in a program. In the case of this function:
How are the variables actually defined? What makes up "total", etc? I see checks for equality, but Im used to seeing something like total = (x * y) or something like that to indicate exactly where total came from. Is this tied in with the precondition somehow? Also, in this particular program, the main does not declare these variables. they only are used here.Code:typedef enum {lost, won, go_on} status; //more functions status turnStatus (int rollNum, int total, int pt) // function: turnStatus // pre: rollNum is 1 or more, total is valid (2 to 12) // post: returns the status of the game (won, lost, or go_on) { if (rollNum == 1) // first roll of the dice if (total == 2 || total == 3 || total == 12) return lost; else if (total == 7 || total == 11) return won; else return go_on; else if (total == 7) return lost; else if (total == pt) return won; else return go_on; }
Any info is appreciated
Thanks,
