用C++写一个俄罗斯方块

很高兴能回答您的问题，请参阅以下示例代码：#include <stdio.h>int main()
{
int i, j, k;
int n; // 俄罗斯方块数

printf("请输入俄罗斯方块的数量：");
scanf("%d", &n);

for (i=1; i<=n; i++)
{
for (j=1; j<=n; j++)
{
for (k=1; k<=n; k++)
{
printf("*");
}
printf("\n");
}
printf("\n");
}

return 0;

用 c++写一个俄罗斯方块

好的，我可以指导您如何用 C++ 写一个简单的俄罗斯方块游戏。

首先，让我们来梳理一下游戏的基本流程和实现：

1. 创建一个游戏窗口并初始化游戏状态。
2. 在窗口上绘制游戏区域和方块。游戏区域可以使用一个二维数组来表示，其中每个元素代表一个方块的状态。
3. 定义方块的形状和颜色，可以使用一个结构体来表示。
4. 实现方块的下落和移动功能，可以使用定时器或者线程控制方块的下落速度和移动方向。
5. 实现方块的旋转功能，可以使用矩阵变换来实现。
6. 处理方块碰撞和消除，当方块落到底部或者与其他方块重叠时，将其固定在游戏区域中。当一行方块都被填满时，将其清除并计分。
7. 实现游戏结束的判定，当游戏区域的顶部出现方块时，游戏结束。

下面是一份简单的 C++ 代码示例，实现了上述的基本功能。注意：此代码仅供参考，并不完整或可用于实际应用。

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <Windows.h>

using namespace std;

const int ROWS = 20; // 游戏区域行数
const int COLS = 10; // 游戏区域列数
const int BLOCK_SIZE = 20; // 方块大小

struct Block {
    int x, y; // 方块左上角坐标
    int shape; // 方块形状
    int color; // 方块颜色
};

int area[ROWS][COLS] = { 0 }; // 游戏区域
Block block; // 当前方块

// 初始化游戏状态
void initGame() {
    srand(time(NULL));
    block.x = COLS / 2 * BLOCK_SIZE;
    block.y = 0;
    block.shape = rand() % 7;
    block.color = rand() % 7 + 1;
}

// 绘制游戏区域
void drawArea(HDC hdc) {
    RECT rc;
    rc.left = 0;
    rc.top = 0;
    rc.right = COLS * BLOCK_SIZE;
    rc.bottom = ROWS * BLOCK_SIZE;
    FillRect(hdc, &rc, (HBRUSH)GetStockObject(WHITE_BRUSH));
    for (int i = 0; i < ROWS; i++) {
        for (int j = 0; j < COLS; j++) {
            if (area[i][j]) {
                rc.left = j * BLOCK_SIZE;
                rc.top = i * BLOCK_SIZE;
                rc.right = rc.left + BLOCK_SIZE;
                rc.bottom = rc.top + BLOCK_SIZE;
                FillRect(hdc, &rc, (HBRUSH)GetStockObject(BLACK_BRUSH));
            }
        }
    }
}

// 绘制方块
void drawBlock(HDC hdc) {
    RECT rc;
    rc.left = block.x;
    rc.top = block.y;
    rc.right = rc.left + BLOCK_SIZE;
    rc.bottom = rc.top + BLOCK_SIZE;
    FillRect(hdc, &rc, (HBRUSH)GetStockObject(BLACK_BRUSH));
}

// 移动方块
void moveBlock(int dx, int dy) {
    int x = block.x / BLOCK_SIZE + dx;
    int y = block.y / BLOCK_SIZE + dy;
    if (x < 0 || x >= COLS || y >= ROWS || area[y][x]) {
        return;
    }
    block.x += dx * BLOCK_SIZE;
    block.y += dy * BLOCK_SIZE;
}

// 旋转方块
void rotateBlock() {

    int x = block.x / BLOCK_SIZE;
    int y = block.y / BLOCK_SIZE;
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {

        }
    }
    for (int i = 0; i < 4; i++) {
        for (int j = 0; j < 4; j++) {
            area[y + i][x + j] = temp[3 - j][i];
        }
    }
}

// 消除方块
void clearBlock() {
    int count = 0;
    for (int i = ROWS - 1; i >= 0; i--) {
        int j = 0;
        for (; j < COLS; j++) {

        }
        if (j == COLS) {
            count++;
            for (int k = i; k > 0; k--) {
                for (j = 0; j < COLS; j++) {
                    area[k][j] = area[k - 1][j];
                }
            }

            }
            i++;
        }
    }
    // 计分
    // ...
}

// 判断游戏结束
