there several ways this. basically, want set flag if 6 occurs, save current sum, roll-again, , take higher of 2 rolls. 1 way implement be:
int eroll = 0; /* flag roll (when b = 6) */ int esum = 0; /* sum (to keep greater of 2 rolls) */ dice_rdme = fopen ("dice_rdme.txt", "w"); { eroll = 0; /* reset eroll */ (a = 0; < plyrset; a++) { b = 1 + rand () % 6; c[j] = b; plyrsum += c[j]; fprintf (dice_rdme, "%i ", c[j]); ++j; if (b == 6) { eroll = 1; /* set eroll flag */ } } if (eroll) { esum = plyrsum; /* save plyrsum */ fprintf (dice_rdme, "extra roll! current sum %i \n", plyrsum); } plyrsum = (plyrsum > esum) ? plyrsum : esum; /* keep best roll */ } while (eroll); output:
$ ./bin/gameeroll commence gamble, test might enter number of rolls wager 3 6 2 3 roll! current sum 11 4 3 3 player score = 21 2 2 3 dealer score = 6 win! student info class professor , ta homework assignment#6 dice game 2.0 note: fprintf inserted testing.
as noted, of equivalences if (a = whatever) need if (a == whatever). need verify remainder of logic in code. c exact language, take time , think each line.
