design requirement ：
1. You won't be killed by thunder for the first time .
2. If it's not thunder, the number of thunder around will be displayed .
3. There's no thunder around , And then it unfolds .
Realization idea ：
1. First, we need to design two mine arrays , One is the mine array used by the designer to store the data of minefield layout , The other is the minefield used by players to clear mines
2. Mine laying ： We need to design one A*A（A Represents the size of the minefield , Design according to the designer's needs ） The thunder array , Cloth has X（X Represents the number of mines , Design according to the needs of designers and players ） A thunder , Then we can use two-dimensional array to realize ray array , Use character ‘1’ It means there is thunder , character ‘0’ No thunder （ If you use numbers 0 and 1 Indicates whether there is thunder , Then there will be ambiguity about whether the number represents thunder or the number of thunder , So this is not the way ）, So the ray matrix is initialized as a character ‘0’, And then use %c To print . Another question is whether we are going to design the mine array into a A*A What's wrong , The answer is No , If you're counting the number of mines around a coordinate , It's going to traverse the surrounding environment A-1 Coordinates , If it's designed to be A*A The thunder array , So there's no space around the outermost coordinates 8 It's a place , So we should design the mine array as （A+2）*(A+2), But mine laying and mine sweeping are only in the middle A*A In progress , In this way, the problem can be solved .
3. mine clearance ： Just like bray , We also need to design the mine array as （A+2）*（A+2）; Because this thunder array is a player's thunder array , In order to increase the mystery , It should be initialized as a character ‘ * ’, Or other characters .
4. Judge whether you win or lose ： Characters in danglei matrix ‘ * ’ also 10 Or the number of demining has reached A*A-X Win the first time .
Specific function implementation ：
1. Enter the menu ： Choose whether to play the game
void mune() { printf("****************************\n"); printf("***** 1. play
*****\n"); printf("***** 0. exit *****\n");
printf("****************************\n"); }
2. Enter the game , Initialize two mine arrays .
void InitBoard(char arr[ROWS][COLS], int rows, int cols,char set) // Initialize mine array {
int i = 0; int j = 0; for (i = 0; i < rows; i++) { for (j = 0; j < cols; j++) {
arr[i][j] = set; } } }
3. Lay out mines in a mine array
void SetMine(char mine1[ROWS][COLS], int row, int col) // Set the distribution of mine array { int count =
EASY_COUNT; while (count) { int x = rand()%row+1; int y = rand()%col+1; if
(mine1[x][y] == '0') { mine1[x][y] = '1'; count--; } } }
4. Print ray array
void DisplayBoard(char mine1[ROWS][COLS], int row, int col) // Print ray array { int i =
0; int j = 0; for (i = 0; i <= row; i++) { printf("%d ", i); } printf("\n");
for (i = 1; i <= row; i++) { printf("%d ", i); for (j = 1; j <= col; j++) {
printf("%c ", mine1[i][j]); } printf("\n"); } }
5. If the coordinate is not ray , Count the number of mines around
int GetMineCount(char mine1[ROWS][COLS], int x, int y) // Count the number of Mines { return
mine1[x - 1][y] + mine1[x - 1][y - 1] + mine1[x][y - 1] + mine1[x + 1][y - 1] +
mine1[x + 1][y] + mine1[x + 1][y + 1] + mine1[x][y + 1] + mine1[x - 1][y + 1] -
8 * '0'; }
6. Avoid being killed by thunder for the first time
void MoveMine(char mine1[ROWS][COLS], char mine2[ROWS][COLS], int row, int
col)// Avoid being killed by thunder for the first time { int x = 0; int y = 0; char ch = 0; int count = 0; int ret =
1; printf(" Mine sweeping by inputting coordinates :>"); while (1) { scanf("%d%d", &x, &y); if (x >= 1 && x <=
row&&y >= 1 && y <= col) { if (mine1[x][y] == '1') { mine1[x][y] = '0'; char ch
= GetMineCount(mine1,x, y); mine2[x][y] = ch + '0'; OpenMine(mine1,mine2, x,
y); while (ret) { int x = rand() % row + 1; int y = rand() % col + 1; if
(mine1[x][y] == '0') { mine1[x][y] = '1'; ret--; break; } } break; } if
(mine1[x][y] == '0') { char ch = GetMineCount(mine1, x, y); mine2[x][y] = ch +
'0'; OpenMine(mine1,mine2, x, y); break; } } else { printf(" Coordinate error , Please re-enter !\n"); }
} }
7. There's no thunder around the coordinates , open
void OpenMine(char mine1[ROWS][COLS], char mine2[ROWS][COLS], int x, int
y)// There's no thunder around the coordinates , It can be expanded { if (mine1[x - 1][y - 1] == '0') { mine2[x - 1][y - 1] =
GetMineCount(mine1,x - 1, y - 1) + '0';// Display the number of mines around the coordinate } if (mine1[x - 1][y] ==
'0') { mine2[x - 1][y] = GetMineCount(mine1, x - 1, y) + '0';// Display the number of mines around the coordinate } if
(mine1[x - 1][y + 1] == '0') { mine2[x - 1][y + 1] = GetMineCount(mine1, x - 1,
y + 1) + '0';// Display the number of mines around the coordinate } if (mine1[x][y - 1] == '0') { mine2[x][y - 1] =
GetMineCount(mine1, x, y - 1) + '0';// Display the number of mines around the coordinate } if (mine1[x][y + 1] == '0') {
mine2[x][y + 1] = GetMineCount(mine1, x, y + 1) + '0';// Display the number of mines around the coordinate } if (mine1[x
+ 1][y - 1] == '0') { mine2[x + 1][y - 1] = GetMineCount(mine1, x + 1, y - 1) +
'0';// Display the number of mines around the coordinate } if (mine1[x + 1][y] == '0') { mine2[x + 1][y] =
GetMineCount(mine1, x + 1, y) + '0';// Display the number of mines around the coordinate } if (mine1[x + 1][y + 1] ==
'0') { mine2[x + 1][y + 1] = GetMineCount(mine1, x + 1, y + 1) +
'0';// Display the number of mines around the coordinate } }
8. Mine sweeping and winning judgment
void FindMine(char mine1[ROWS][COLS], char mine2[ROWS][COLS], int row, int
col) // mine clearance { int x = 0; int y = 0; int win = 0; while (win<row*col-EASY_COUNT) {
printf(" Please enter the coordinates to be checked ：>"); scanf("%d%d", &x, &y); if (x >= 1 && x <= row&&y >= 1 &&
y <= col) { if (mine1[x][y] == '1') { printf(" unfortunately , You were killed in the blast !\n");
DisplayBoard(mine1, row, col); break; } else { int count = GetMineCount(mine1,
x, y); mine2[x][y] = count + '0'; DisplayBoard(mine2, row, col); } } else {
printf(" Illegal coordinates , Please re-enter !\n"); } } if (win == row*col - EASY_COUNT) {
printf(" congratulations , Successful demining !\n"); } }

Results display ：
Choose whether to enter the game or not ：
Enter the game , Start minesweeping
Enter coordinates , And show the number of mines around , And unfold .
Sweep to thunder , The game failed
summary ： Before writing any program, the first thing to do is to analyze its logical thinking , Make the logic clear , The next step is to use syntax to achieve the goal , And we need to pay attention to the details , Wrong. It's hard to find a detail after debugging for a long time , We should also pay attention to the optimization of time and space ; Be careful in the process of writing , Pay attention to parameter transfer and function call , You also need to pay attention to the use of brackets , Ensure readability .
