The code is completed in a project and divided into three .c.h files (game.c, game.h, main.c)
and debugged by running in Clion software.
/General idea/
The main function main.c is a large frame (menu, minesweeper board Initialization, random function generates mines, players clear mines)
game.h function declaration (some function declarations except main function and game function)
game.c function Implementation (implementation of some functions except main function and game function)
/game.c实现/
① First initialize the minesweeper board (use two character arrays of the same size as the minesweeper board
1. Store mines 2. Display the minesweeper board to the player. In order to avoid traversing There is an out-of-bounds access in , the board size is set to 11*11, mines are arranged in the size of 9*9, and the player is also shown to 9< a i=4>9 size. Equivalent to hiding the first and last rows, the first and last columns.) 1 The chessboard is initialized to 0 2 The chessboard is initialized to **
②After initializing the chessboard, display the chessboard
③Random function generates mines and stores them in the first character array
④Player minesweeper implementation includes: Player Enter whether the coordinate position is mine. If the coordinates are not mines, are there mines in the surrounding circle? When the coordinates are not mines and there are no mines around, recursion is used to display these coordinates as empty.
The following are some function implementations:
//Determine how many mines are around (get the mine number information at eight positions in a circle except the input coordinates.
For characters, a certain character -'0' is Integer. Eight coordinates minus eight '0's are the number of mines in the eight coordinates)
//判断周围多少雷，返回雷数
int BombNumber(char mine[ROWS][COLS],int row,int col){
return mine[row -1][col-1] + mine[row - 1][col] + mine[row - 1][col+1] + \
mine[row][col-1] + mine[row][col+1] + \
mine[row+1][col - 1] + mine[row+1][col] + mine[row+1][col+1] -8*'0';
}
Originally, when the coordinates entered by the player were not mines, and the eight surrounding coordinates were not mines, I wanted to list the nine coordinates in the function and save them as empty before displaying them. But in the learning video, it is mentioned that recursion can be used to present a blank chessboard. I looked up other people's code online and learned how to use recursion to render a chessboard.
//假设是3*3的棋盘
show[row - 1][col - 1] = ' ';//第一行
show[row - 1][col] = ' ';
show[row - 1][col + 1] = ' ';
show[row][col - 1] = ' ';//第二行
show[row][col] = ' ';
show[row][col + 1] = ' ';
show[row + 1][col - 1] = ' ';//第三行
show[row + 1][col] = ' ';
show[row + 1][col + 1] = ' ';
Recursively present a chessboard
//The recursive idea in this code is 1. The coordinate is not a mine 2. The eight surrounding coordinates are not a mine either
Loop through the coordinates entered by the player nine times to determine whether each coordinate is legal and has no mines and is not displayed to the player
After the coordinates meet the conditions, the function to determine whether there are mines in a circle is called. If the loop If there is no thunder in a circle of a certain coordinate, it will enter the recursive function again, and then loop through the coordinates of the coordinate to continue the above process. If the coordinates do not meet the conditions, the recursion will end and the else statement will be entered until the nine loops are completed.
