Multiple Choice

A 9-hole golf course is introducing an app to replace paper scorecards. The total score is the number of times the player hits the ball to complete all 9 holes.

Each hole has a target score known as the par value.

If a score entered is three or more above the par value for that hole it is

adjusted to the par value plus two. This is shown for holes 3 and 6.

Part of the code for the app is shown below.

…

Line 10 REPEAT 9 TIMES

Line 11 RECEIVE par FROM (INTEGER) KEYBOARD

Line 12 RECEIVE score FROM (INTEGER) KEYBOARD

Line 13 < calculate final score for each hole >

Line 14 < update totalScore >

Line 15 END REPEAT

Line 16 SEND totalScore TO DISPLAY

Choose the correct code for line 13.

• if score > par+2:

  score = par+2

• if score > par:

  score = par+2

• if score == par+2:

  score = par+2

• if score < par+2:

  score = par+2
