Thread: Craps Game, possibly logical error with enumeration constant

Below is the code to my craps game, Im using enumeration constants for game status to determine whether to continue or not.

The Problem: After Crapping Out, the enumeration gameStatus evaluated to LOSE (confirmed by printf()), but the loops condition: while(gameStatus == CONTINUE ), evaluated to true. Why did my enumeration revert back to its previous state?

your printfs don't really show the sequence of what is happening. i set a breakpoint on line 167 where it hits LOSE. the program exits the while loop as expected, but the main loop doesn't detect the LOSE so it keeps rolling the dice and you get back to the while(gamestatus==continue) line.
