Mine-Sweeper-Game

Minesweeper Game in C++

Introduction

• Objective: Create a Minesweeper game in C++.
• Tools Used: Standard C++ libraries for input-output, mathematical calculations, string operations, and time-related functions.

Game Setup

• Macros and Global Variables

  • BEGINNER, INTERMEDIATE, ADVANCED: Difficulty levels
  • MAXSIDE: Maximum board side length
  • MAXMINES: Maximum number of mines

• Global Variables

  • SIDE: Current board side length
  • MINES: Current number of mines

Utility Functions

1. isValid(row, col)

   • Checks if a cell (row, col) is within the board.

2. isMine(row, col, board)

   • Checks if a cell contains a mine.

3. makeMove(x, y)

   • Gets user's move input.

4. printBoard(myBoard)

   • Prints the current game board.

5. countAdjacentMines(row, col, mines, realBoard)

   • Counts adjacent mines for a given cell.

Game Logic

1. playMinesweeperUtil(myBoard, realBoard, mines, row, col, movesLeft)

   • Recursive function to play the game.

2. placeMines(mines, realBoard)

   • Places mines randomly on the board.

3. initialise(realBoard, myBoard)

   • Initializes the game board.

4. cheatMinesweeper(realBoard)

   • Reveals mine locations (cheat mode).

5. replaceMine(row, col, board)

   • Replaces a mine with an empty space.

Main Game Function

• playMinesweeper()
  • Main game loop.
  • Displays the current board.
  • Handles user moves and game outcomes.

---

Game Initialization and Difficulty Selection

• chooseDifficultyLevel()

  • Allows the user to select the game difficulty.

• main()

  • Entry point of the program.
  • Calls chooseDifficultyLevel and playMinesweeper.

Description

• The Minesweeper game begins by prompting the user to select a difficulty level: Beginner, Intermediate, or Advanced. Based on the chosen level, the board's side length and the number of mines are determined.
• Two 2D arrays, realBoard and myBoard, are initialized to represent the actual game board and the player's view, respectively. Initially, all cells on both boards are set to -, indicating they are empty.
• Mines are then randomly placed on the realBoard according to the selected difficulty level, and their positions are stored in the mines array. The main game loop (playMinesweeper function) continues until either a mine is opened or all non-mine cells are revealed (movesLeft becomes 0).
• During each iteration, the current state of myBoard is displayed using printBoard. The player selects a cell by entering its row and column coordinates. If it's the first move and the selected cell is a mine, the mine is relocated to ensure the player's first move is safe.
• For each empty cell selected, the number of adjacent mines is calculated and displayed on myBoard using countAdjacentMines. If a cell with a mine is opened, the game ends with a "You lost!" message, revealing all mine locations. Conversely, if all non-mine cells are opened, the game concludes with a "You won!" message.
• Additionally, the game offers a cheat mode (cheatMinesweeper) to view mine locations and a feature to replace a mine (replaceMine) to guarantee the player's first move safety.

Conclusion

• The game uses a 2D array to represent the board.
• Mines are randomly placed based on the selected difficulty.
• Players reveal cells to find non-mine areas.
• The game ends if a mine is revealed or all non-mine cells are opened.
