C++写一个俄罗斯方块

很高兴回答你的问题。以下是一个简单的俄罗斯方块的 C 代码示例：

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

#define WIDTH 10
#define HEIGHT 20

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

{{, }, {, 1}, {1, }, {1, 1}}, // O
{{, }, {, 1}, {, 2}, {, 3}}, // I
{{, }, {, 1}, {, 2}, {1, 2}}, // L
{{, }, {, 1}, {, 2}, {-1, 2}}, // J
{{, }, {, 1}, {1, 1}, {1, 2}}, // S
{{, }, {, 1}, {-1, 1}, {-1, 2}}, // Z
{{, }, {, 1}, {, 2}, {1, 1}} // T
};

}
}

}
