Bowling Notes

Basic Program Structure​

Three main components

  • inputPlayerRolls: input all 21 rolls for the player and store them in a vector. If a strike happens, only input one roll for that frame. If there is a strike or spare on the last frame, input the 21st roll.

  • calculatePlayerScore: take the 21 rolls from the player and calculate their score. NOTE: You do not calculate the scores until all the rolls have been entered, this is much harder than doing it after.

  • printGameSummary: print out all the players and their scores and print out the best and worst scores. If no players were entered, print "No players were entered."

Scoring Examples​

Bowling calculator

Spare: add current frame roll 1 + current frame roll 2 + next frame roll 1

Frame 1: 5 + 5 + 6 = 16

spare

Strike: add current frame roll 1 + next frame roll 1 + next frame roll 2

Frame 1: 10 + 3 + 4 = 17

strike

Double strike: add current frame roll 1 + next frame roll 1 + next next frame roll 1

Frame 1: 10 + 10 + 5 = 25

double-strike

Frame 10 spare: add frame 10 roll 1 + roll 2 + roll 3

frame10-spare

Frame 10 strike: add frame 10 roll 1 + roll 2 + roll 3

frame10-strike

Frame 9 double strike edge case: add frame 9 roll 1 + frame 10 roll 1 + frame 10 roll 2 (not frame 10 roll 3)

Frame 9: 10 + 10 + 3 = 23 (not 10 + 10 + 2)
