Question

Aim:

By working on this assignment you should be able to:

● Create and use dynamic arrays

● Create, manipulate and store input in c-style strings

● Accept and parse command-line arguments

● Implement recursion

About this assignment:

For this assignment, you will design and implement a game. You can pick between minesweeper or battleship. If you turn in both, you will get whichever scores the highest points. If you submit the design for one option, but code for another, you would lose all the points on the design.

Problem statement:

The objective of the game is to open/reveal every cell on the board without detonating a mine. Every cell contains a number or a mine. The numbers tell you how many mines surround the cell in the ​horizontal ​ , ​vertical ​ , and ​diagonal directions, e.g. at most, 8 possible mines surrounding a cell. You can flag a cell, which helps you remember where you think there is a mine to not detonate. If you select to open/reveal a cell that has a mine, then you automatically lose the game!

When the user runs the game program, they would pass command-line arguments telling the number of rows, columns and mines that they want in the game. The game would randomly distribute the mines on the board and setup the numbers describing how many adjacent mines are to each cell. After that, the game will display a blank board and ask the user to flag or open a cell on the board until the user selects a cell that contains a mine (losing the game) or selects all the cells free of mines (winning the game).

After the user wins or loses, you will ask the user if they want to play again. If so, you must get the number of rows, columns, and mines for the new game and create a new board for a new game.

When the user decides to quit the game, you would display their score as number of mines the user stepped on and number of mines cleared(the ones they didn’t step on) taking into consideration all the games the user played since the program was run.

Tip:​ You can display row and column numbers on board to make it easier for the user to read/know which row and column to select!

Requirements:

● You must provide a message telling which command line arguments are acceptable and how to pass them, if the user enters incorrect command-line arguments. Include an example!

● The user should be able to specify command line arguments in any order.

● You must not have functions over 15-20 lines long (-10 automatically)

● You must not use global variables (-10 automatically)

● After the user wins/loses, you must ask if they want to play again ○ If no, then end the game while displaying the total number of mines stepped and cleared for all the attempts the user played the game

○ If yes, then prompt for rows, cols, and mines for new game.

● You must not have any memory leaks (-10 automatically)

● You must detect these errors:

○ Invalid row or column to flag or open

○ Opening a cell that has already been opened

○ Flagging a cell that has been already flagged

Example run:
