CSC171 — Project 2

TTY Golf

In this project you will build on your first project experience and develop a TTY program to

play the game of Golf. It doesn’t matter if you know how golf works—the rules of the game

that you need to implement our version are described below. And of course you can look it

up on Wikipedia: Golf.

As with Project 1, the basic idea is that the program will tell the player the game situation and

offer them a choice of various actions. The player will type their choices and the program will

read them, compute the result, and inform the user. This is essentially what you did last time,

only for a more complicated and realistic game. You may also, for extra credit, implement a

computer opponent that plays against the human.

This document contains a lot of information. First it describes the game of golf generally, and

then the abstract version of it that we will use for our TTY game. An example of what the

output of your program might look like is provided. You should be able to start thinking about

your program after reading these.

The section “Specifications” provides all the details that you need to put into your program in

order to actually play the game. The section “Project Design and Requirements” describes

the main aspects of the project and gives some suggestions on how to approach them. The

section “Specific Requirements” spells out exactly what your program must do. Grading

details, opportunities for extra credit, and other policy details are at the end of the document.

The Game of Golf (Simplified)

The game of golf is played on a mostly grass-covered golf course (see Figure ). A course

consists of 18 holes. Each hole is a more or less linear span of the course’s grassy terrain.

Each hole has a tee at one end, where the players start, and a green, where the grass is

cut very short, at the other end. Someplace on the green is an actual, physical hole (or cup)

marked by a flag.

Each player uses a set of golf clubs to hit their ball around the course. Each club has different

characteristics, but roughly speaking the farther a club can hit, the less accurate it is. Each

hit is called a shot or stroke.

The first shot on each hole is taken from the tee. Most holes are too long for the tee shot to

reach the green and get into the hole. Subsequent shots are played from where the previous

shot lands and stops. Once the ball reaches the green, the player uses a special club called

a putter (PUH-ter) to putt (PUHT) or tap the ball towards the hole. Getting the ball to fall into

the hole is called “sinking the putt.”

The goal of the game is to get the ball into the hole in as few strokes (shots) as possible.

Each hole is assigned an “expected” number of strokes, called its par. Completing a hole in

that number of strokes is called “making par.” Completing a hole in fewer strokes is called

being “under par;” completing it in more strokes is called being “over par.”

A full game, also called a round, involves playing all 18 holes of a course in turn. A player’s

score for a round is the total number of strokes they used to complete the course. This is

traditionally expressed as the difference from the total par for the course. Thus finishing in

one less stroke than par is “-1” (“one under”), while finishing in one more stroke is “+1” (“one

over”).

In the real game, each hole is a part of the landscape of the course. For our game, we will

ignore almost everything about the physical topography of the course. The holes will simply

have a distance from tee to hole. All greens will be a fixed size and it won’t matter where on

the green the hole is placed.

TTY Golf

In TTY Golf, a course is represented as a set of 18 holes, each of which has a yardage

(number of yards from tee to hole) and a par for the hole.

The player will play each hole of the course in turn to complete their round.

For each stroke (shot) other than putting, the player will select a club (a number 1–10) and

the power with which to hit the ball (also a number 1–10). Your program will compute the

distance of the shot (details below) and inform the user of the result.

The player will continue to take shots like this until ball is within 20 yards (60 feet) of the hole,

at which point it is on the green.

Once the ball is on the green, the player putts by specifying the power with which to hit the

ball (1–10). Your program will compute the distance of the putt and whether it goes in the

hole (details below). The player continues to putt until the ball is in the hole.

Your program will keep track of the number of strokes (shots) and the player’s score relative

to the total par of the holes they have played so far.

When the game is over, your program should offer to play a new round or quit.

Sample Transcript

The following transcript is a purely hypothetical example of the sort of gameplay that your

program might provide. It should give you some idea of the sorts of messages and prompts

that are necessary. But you do NOT have to make your game play exactly like this. The

important thing is to keep the player informed about the game situation. Be very clear what

you’re asking for when prompting for user input.

Clubs

Obviously in real-life, how far the ball travels when it is hit depends on the player, the club,

and how the ball is hit. For TTY Golf, things are much simpler. We will assume the following

specifications for the different golf clubs (based on source: about.com):
