C language implements simple minesweeper games

This article is an example of C language to share the implementation of simple minesweeper game code, for your reference, the specific content is as follows

steps

1. First print the game selection menu
2. Map and initialization
1) Map shown to players (show_map)
2) Map of the mine (mine_map knows the location of the mine)
Print the map
4. User input coordinates and check the rationality of coordinates
5. Determine whether there are mines in the current position, and if there are no mines, a number will appear (indicating how many mines are in the surrounding grid).
Print a new map
7. Repeat steps 3-6 until the thunder game is over or you win.
Resume the game or quit!

code

Main function and game selection menu

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
 
#define ROW 9
#define COL 9
#define COUNT 10 // Number of mines 
 
int menu()
{
 printf("*************************\n");
 printf("****** 1.play ******\n");
 printf("****** 0.exit ******\n");
 printf("*************************\n");
 printf(" Please select a :>");
 int choice = 0;
 scanf("%d", &choice);
 return choice;
}
 
int main()
{
 int choice = 0;
 srand((unsigned int)time(NULL));
 while (1)
 {
 choice = menu();
 if (choice == 1)
 {
 game();
 }
 else if (choice == 0)
 {
 printf("goodbye!\n");
 break;
 }
 else
 {
 printf(" Input error, please re-input! \n");
 }
 }
 
 system("pause");
 return 0;
} 

~ Enter the game

1. Create two 2-dimensional arrays; 2. Initialize two 2-dimensional arrays; 3. Print the map; 4. Let the user input 1 set of coordinates; 5. Determine whether to step on a mine; 6. Judge whether the game is won or not; 7. Update the map to change the current location to a number (the number is the number of mines in the surrounding grid).

void game()
{
 //1. Create two 2 Dimensional array 
 char show_map[ROW][COL];
 char mine_map[ROW][COL];
 //2. The two 2 The dimension array is initialized 
 Init(show_map, mine_map); 
 int blank_count = 0;
 while (1)
 {
 PrintMap(mine_map);// To facilitate debugging, print temporarily mine_map
 printf("\n");
 
 //3. Print the map 
 PrintMap(show_map);
 //4. Let the user enter 1 Set of coordinates 
 printf(" Please enter coordinates :>");
 int i = 0;
 int j = 0;
 scanf("%d %d", &i, &j);
 if (i < 0 || i >= ROW || j < 0 || j >= COL)
 {
 printf(" Input error, please re-input! \n");
 continue;
 }
 if (show_map[i][j] != '*')
 {
 // This position has been flipped 
 printf(" The input position has been turned over, please re-enter! \n");
 continue;
 }
 //5. Decide whether to step on a mine 
 if (mine_map[i][j] == '1')
 {
 // Step on thunder, prompt game is over 
 PrintMap(mine_map);
 printf(" Game over !\n");
 break;
 }
 blank_count++;
 //6. Whether the game wins 
 if (blank_count == ROW * COL - COUNT)
 {
 printf(" Congratulations, mine clearance is a success !\n");
 break;
 }
 //7. Update the map to change the current location to 1 A digital 
 UpdateShowMa(show_map, mine_map, i, j);
 }
}

Initialization map

void Init(char show_map[ROW][COL], char mine_map[ROW][COL])
{
 //1.show_map  All initialized to  *
 for (int i = 0; i < ROW; i++)
 {
 for (int j = 0; j < COL; j++)
 {
 show_map[i][j] = '*';
 }
 }
 //2.mine_map Initialize the 
 for (int i = 0; i < ROW; i++)
 {
 for (int j = 0; j < COL; j++)
 {
 mine_map[i][j] = '0';
 }
 }
 //3. Randomly generated 10 Three locations as mines 
 int mine_count = COUNT;
 while (mine_count > 0)
 {
 // Generate random coordinates 
 int i = rand() % ROW;
 int j = rand() % COL;
 if (mine_map[i][j] == '1')
 {
 continue;
 }
 mine_map[i][j] = '1';
 --mine_count;
 }
}

Print the map

void PrintMap(char map[ROW][COL])
{
 //1. Print the first 1 Row (coordinate) 
 printf(" |");
 for (int j = 0; j < COL; j++)
 {
 printf(" %d", j);
 }
 printf("\n");
 //2. print 1 Line separators 
 for (int j = 0; j < COL; j++)
 {
 printf("---");
 }
 printf("\n");
 //3. Print each line separately 
 for (int i = 0; i < ROW; i++)
 {
 printf(" %d|", i);
 for (int j = 0; j < COL; j++)
 {
 printf(" %c", map[i][j]);
 }
 printf("\n");
 }
}

Determine the number of grid mines around the drop

void UpdateShowMa(char show_map[ROW][COL], char mine_map[ROW][COL], int i, int j)
{
 // Determine the current position ( i . j ) , around 8 There are several mines in this grid 
 int count = 0;
 if (i - 1 >= 0 && j - 1 >= 0 && mine_map[i - 1][j - 1] == '1')
 { 
 count++;
 }
 if (i - 1 >= 0 && mine_map[i - 1][j] == '1')
 {
 count++;
 }
 if (i - 1 >= 0 && j + 1 < COL && mine_map[i - 1][j + 1] == '1')
 {
 count++;
 }
 if (j - 1 >= 0 && mine_map[i][j - 1] == '1')
 {
 count++;
 }
 if (j + 1 < COL && mine_map[i][j + 1] == '1')
 {
 count++;
 }
 if (i + 1 < ROW && j - 1 >= 0 && mine_map[i + 1][j - 1] == '1')
 {
 count++;
 }
 if (i + 1 < ROW && mine_map[i + 1][j] == '1')
 {
 count++;
 }
 if (i + 1 < ROW && j + 1 < COL && mine_map[i + 1][j + 1] == '1')
 {
 count++;
 }
 //count  The value inside is already the number of surrounding mines 
 show_map[i][j] = count + '0';
}
