写c语言俄罗斯方块小游戏

下面是一个简单的C语言俄罗斯方块小游戏的示例代码：

#include <stdlib.h>
#include <conio.h>
#include <windows.h>

#define WIDTH 10
#define HEIGHT 20

int board[HEIGHT][WIDTH] = {0};

int currentX = 0;
int currentY = 0;

void drawBoard();
void drawPiece();
void clearPiece();
void rotatePiece();
int checkCollision(int newX, int newY, int newPiece[4][4]);

int main() {
    int gameOver = 0;
    int key = 0;

    // 设置控制台窗口大小
    HWND console = GetConsoleWindow();
    RECT r;
    GetClientRect(console, &r);
    MoveWindow(console, r.left, r.top, 400, 600, TRUE);

    // 游戏循环
    while (!gameOver) {
        // 处理键盘输入
        if (_kbhit()) {
            key = _getch();
            switch (key) {

}

这个示例代码使用了Windows系统的conio.h和windows.h头文件来实现控制台窗口和键盘输入的功能。在游戏循环中，根据键盘输入移动和旋转方块，并根据方块的位置判断是否发生碰撞。游戏结束时，输出"Game Over!"并结束程序的运行。

请注意，这只是一个简单的示例代码，并没有实现游戏的所有功能和特性。你可以根据自己的需求对代码进行修改和扩展
