INT2067 Introduction to Programming and Problem Solving

2024-2025 Semester 1

Due Date: October 30, 2024 (Wednesday)

1 Introduction

In this assignment, you need to implement a text-based game based on the riddle abouta farmer who needs to cross a river with a fox, a goose, and a sack of corn.

2 Riddle

A farmer with a fox, a goose, and a sack of corn needs to cross a river. The farmer has arowboat, but there is room for only the farmer and one of her three items.Unfortunately, both the fox and the goose are hungry. The fox cannot be left alone withthe goose, or the fox will eat the goose. Likewise, the goose cannot be left alone withthe sack of corn, or the goose will eat the corn. How does the farmer get everythingacross the river?

3 Game

In your text-based game, the farmer can move at most one item to the other shore eachtime. You should ask the user to enter a command to determine what item the farmerwants to take at each turn. The game ends when the user quits the game or when theuser has succeeded or failed.

4 Basic Design

You may follow the following basic flow in your program:

 Show item locations.

 Repeat:

1. Ask for the next command.
2. Update item locations if necessary.
3. Show item locations.
4. Exit the loop if the game has succeeded or failed.

You may need to add other steps and/or flows to fulfill all the requirements. 5 Requirements (70%)Your program should do the following:

 [5%] Print the goal of the game at the start.

 [10%] Ask the user to enter a command at each turn and continue until the userrequests to quit or the goal has succeeded or failed.

 [10%] Show the location of the boat and the three items (fox, goose, corn) clearlyat the start of the game and after each turn. You may follow the output in thesample session.

 Accept the following five one-character strings as valid commands: f, g, c, m orAfter receiving a valid command, the game should:

o f, g or c: move the fox, goose, or corn, if available, to the opposite shorealong with the boat. [10%]o m: move the boat to the opposite shore without any item. [5%]oq: quit the game. [5%] [10%] Check whether 代写INT2067 Introduction to Programming and Problem Solving the requested item is on the same shore as the boat whenthe game receives the command f, g or c. If not, it should prompt an error andallow the user to enter a command again.

 [10%] Check whether the game has succeeded or failed after each turn. Thegame has succeeded if all items have been moved to the far shore. The gamehas failed if the fox has eaten the goose, or the goose has eaten the corn. Whenthe game has succeeded, it should congratulate the user. When the game hasfailed, it should tell the user why.

 [5%] Show an error if the user has entered an unrecognized command character(i.e. a string other than ‘f’, ‘g’, ‘c’, ‘m’ or ‘q’).

6 Program Design and User Interface (30%)

 [10%] You should break down your program into functions with reasonablelength.

 [10%] You should use functions and/or lists to reduce redundancy.

 [10%] The output should be neat, and the required information should be shownclearly. The text in the output should be correct and contain no spellingmistakes. 7 Submission Requirements

 Your Python file should be named as assignment1.py. Submit only the Pythonfile assignment1.py through Moodle. Failure to submit the file properly willresult in a penalty of 5 to 20 marks.

 See Moodle for the exact time of the deadline for submission. Late submission isusually not accepted. You should submit earlier to avoid possibly high traƯ ic

around the deadline.

8 Hints

Please check the discussions forum on Moodle regularly for any hints.

9 Plagiarism PolicyThe assignment should be done only by yourself. Every line of code should be written byyou. Discussions on the assignment should be kept at a high-level only. You arsuggested to refer your classmates to the relevant notes or lab exercises if you want tohelp them.

If cheating is found, both the copier and originator will get zero mark for the

assignment.

Repeat oƯ enders may result in a deduction of the course grade.If you have discussed the assignment with anyone, you should provide anacknowledgment at the end of your program file. Give the names of all classmates thatyou have discussed with. For example, your acknowledgement may look like this at theend of your program file:# Acknowledgement: I have discussed it with Thomas, Gordon, and Emily. 10 Sample Session 1
