Three-game as a classic game for the beginner C language proficiency if we can understand and can implement its gaming capabilities, the future for a more systematic study of C language has a good help. Down I share my insights and codes when programming
First, tell us about the three-game rule: as long as your chess even as a line (row, column, diagonal), that is to win
as shown:
The first and FIGS play roughly and ideas:
1. We can checkerboard seen as a two-dimensional array of three rows and three columns, each column and each row separated by lines to distinguish
2 into computer chess and chess players (computer players at first and the first under)
3. determine winning or losing (the player wins, a draw and win computer)
The above analysis is the general idea, let's start writing code:
Creating tset.c, game.c and head.h three documents
1. Write a main function in test.c and write the game menu
Here I am into computers to the next and the first player, the code is as follows;
void menu()
{
printf("***************************************\n");
printf("* 1.play 0.exit *\n");
printf("***************************************\n");
}
void first_move()
{
printf("***************************************\n");
printf("* 1.computer first 2.player first *\n");
printf("***************************************\n");
}
void game()
{
return 0；
}
int main()
{
int choice;
srand((unsigned int)time(NULL));//产生随机数
do
{
menu();
printf("请选择:");
scanf("%d", &choice);
switch (choice)
{
case 1:
game();
break;
case 0:
break;
default:
printf("输入错误请重新输入.\n");
break;
}
} while (choice);
return 0;
}2. game.c down gradually to achieve the desired function and call function in game
Print out the board, and the board is initialized to spaces. code show as below;
void show_board(char board[ROWS][COLS], int rows, int cols)//打印棋盘
{
int i;
for (int i = 0; i < rows; i++)
{
printf(" %c | %c | %c \n", board[i][0], board[i][1], board[i][2]);
if (i != rows - 1)
printf(" ---|---|--- \n");
}
}
void init_board(char board[ROWS][COLS], int rows, int cols)//将数组初始化为空格
{
int i, j;
for (i = 0; i < rows; i++)
{
for (j = 0; j < cols; j++)
{
board[i][j] = ' ';
}
}
}Results shown in Figure
3. Write code players Lazi
The number of players enter the coordinates of two-dimensional array, then need to determine whether the player is reasonable coordinate input on this coordinate, and whether there are pieces, as follows;
void player_move(char board[ROWS][COLS], int rows, int cols)//玩家落子
{
int x, y;
printf("玩家落子:\n");
while (1)
{
scanf("%d %d", &x, &y);
if (x >= 1 && x <= rows && y >= 1 && y <= cols)
{
if (board[x - 1][y - 1] == ' ')
{
board[x - 1][y - 1] = '*';
break;
}
else printf("位置已被占用！请再试一次。\n");
}
else printf("输入错误!请重新输入.\n");
}
}4. play into the computer zi
Here is a computer-generated random Lazi achieved in a space array. code show as below;
void computer_move(char board[ROWS][COLS], int rows, int cols)// 电脑落子
{
int x, y;
printf("电脑落子:\n");
while (1)
{
x = rand() % rows;
y = rand() % cols;
if (board[x][y] == ' ')
{
board[x][y] = '#';
break;
}
}
}5. Finally, it only determines winners and losers
First discuss the winning player or computer; code is as follows;
char check_win(char board[ROWS][COLS], int rows, int cols)//判断输赢
{
int i;
for (i = 0; i < rows; i++)
{
if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')
return board[i][1];
}
for (i = 0; i < cols; i++)
{
if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != ' ')
return board[1][i];
}
if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ')
return board[1][1];
else if (board[2][0] == board[1][1] && board[1][1] == board[0][2] && board[1][1] != ' ')
return board[1][1];
else if (is_full(board, rows, cols))
return 'q';
return 0;
}This is considered a event of a tie, a draw was the next full board are not winning or losing, you can traverse the entire array (the board) if there is no space on a draw. code show as below;
static int is_full(char board[ROWS][COLS], int rows, int cols)//检测是否为平局
{
int i, j;
for (i = 0; i < rows; i++)
{
for (j = 0; j < cols; j++)
{
if (board[i][j] == ' ')
return 0;
}
}
return 1;
}Preliminary test results are as follows
In the figure we can see that the computer can have a chance to win it at random Now, this game is no challenge. Should therefore be modified under erupted computer code, make it intelligent. We determined if the computer zi pieces in the same peer, or column with a slash, the computer at which the spaces preferentially Zi unpaired one line, so that simple intelligent
code show as below;
void computer_move(char board[ROWS][COLS], int rows, int cols)//智能化电脑落子
{
int x, y, i;
printf("电脑落子:\n");
while (1)
{
x = rand() % rows;
y = rand() % cols;
for (i = 0; i < rows; i++)
