linux中C语言2048

2048是一个非常流行的数字游戏，也可以在Linux中使用C语言编写。下面是一个简单的2048游戏示例代码：

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

#define ROWS 4
#define COLS 4

// 初始化数组
void init(int board[][COLS])
{
    int i, j;
    for (i = 0; i < ROWS; i++) {
        for (j = 0; j < COLS; j++) {
            board[i][j] = 0;
        }
    }
}

// 随机生成一个数字
void generate_number(int board[][COLS])
{
    int i, j;
    int count = 0;
    int num;
    int empty[ROWS * COLS][2];

    for (i = 0; i < ROWS; i++) {
        for (j = 0; j < COLS; j++) {
            if (board[i][j] == 0) {
                empty[count][0] = i;
                empty[count][1] = j;
                count++;
            }
        }
    }

    if (count == 0) { // 没有空位，不能生成
        return;
    }

    srand(time(NULL));
    num = rand() % 2 + 1; // 随机生成1或2
    i = rand() % count;
    board[empty[i][0]][empty[i][1]] = num;
}

// 打印数组
void print_board(int board[][COLS])
{
    int i, j;
    for (i = 0; i < ROWS; i++) {
        for (j = 0; j < COLS; j++) {
            printf("%4d", board[i][j]);
        }
        printf("\n");
    }
    printf("\n");
}

// 合并相同的数字
void merge(int board[][COLS])
{
    int i, j, k;
    for (i = 0; i < ROWS; i++) {
        for (j = 0; j < COLS; j++) {
            if (board[i][j] != 0) {
                for (k = j + 1; k < COLS; k++) {
                    if (board[i][k] == board[i][j]) {
                        board[i][j] *= 2;
                        board[i][k] = 0;
                        break;
                    } else if (board[i][k] != 0) {
                        break;
                    }
                }
            }
        }
    }
}

// 移动数字
void move(int board[][COLS], char dir)
{
    int i, j, k;
    switch (dir) {
        case 'w': // 上
            for (j = 0; j < COLS; j++) {

在Linux中使用gcc编译运行：

gcc -o 2048 2048.c
