c 语言五子棋源代码

五子棋是一种非常经典的棋类游戏，以下是一份简单的C语言五子棋源代码，可以供你参考：

#include <stdio.h>
#include <stdlib.h>

#define SIZE 15
#define BLACK 'X'
#define WHITE 'O'
#define EMPTY '+'

char board[SIZE][SIZE];
char player = BLACK;

void init_board() {
    int i, j;
    for (i = 0; i < SIZE; i++) {
        for (j = 0; j < SIZE; j++) {
            board[i][j] = EMPTY;
        }
    }
}

void display_board() {
    int i, j;
    printf(" ");
    for (i = 0; i < SIZE; i++) {
        printf("%d", i+1);
    }
    printf("\n");
    for (i = 0; i < SIZE; i++) {
        printf("%c", i+'A');
        for (j = 0; j < SIZE; j++) {
            printf("%c", board[i][j]);
        }
        printf("\n");
    }
}

int get_input(int *row, int *col) {
    char input;
    printf("%c's turn: ", player);
    if (fgets(input, 3, stdin) == NULL) {
        return 0;
    }
    *row = input - 'A';
    *col = input - '1';
    return 1;
}

int check_win(int row, int col) {
    int i, j;
    char symbol = board[row][col];
    int count = 1;

    for (i = row-1; i >= 0 && board[i][col] == symbol; i--) count++;
    for (i = row+1; i < SIZE && board[i][col] == symbol; i++) count++;
    if (count >= 5) return 1;

    count = 1;
    for (j = col-1; j >= 0 && board[row][j] == symbol; j--) count++;
    for (j = col+1; j < SIZE && board[row][j] == symbol; j++) count++;
    if (count >= 5) return 1;

    count = 1;
    for (i = row-1, j = col-1; i >= 0 && j >= 0 && board[i][j] == symbol; i--, j--) count++;
    for (i = row+1, j = col+1; i < SIZE && j < SIZE && board[i][j] == symbol; i++, j++) count++;
    if (count >= 5) return 1;

    count = 1;
    for (i = row-1, j = col+1; i >= 0 && j < SIZE && board[i][j] == symbol; i--, j++) count++;
    for (i = row+1, j = col-1; i < SIZE && j >= 0 && board[i][j] == symbol; i++, j--) count++;
    if (count >= 5) return 1;

    return 0;
}

void change_player() {
    if (player == BLACK) {
        player = WHITE;
    } else {
        player = BLACK;
    }
}

int main() {
    int row, col;
    init_board();
    display_board();
    while (get_input(&row, &col)) {
        if (board[row][col] != EMPTY) {
            printf("This cell is already occupied!\n");
            continue;
        }
        board[row][col] = player;
        display_board();
        if (check_win(row, col)) {
            printf("%c wins!\n", player);
            break;
        }
        change_player();
    }
    return 0;
}

这个程序使用了一个二维数组来表示棋盘，其中'X'表示黑棋，'O'表示白棋，'+'表示空位。游戏过程中，玩家通过输入棋子的坐标来下棋，程序会检查下的位置是否合法，如果合法则将该位置上的棋子改为当前玩家的棋子，并检查是否有玩家获胜。如果有一方获胜，则游戏结束。
