别踩白块儿c语言代码

以下是一个简单的别踩白块儿C语言代码的实现：

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

#define ROW 10
#define COL 10

int main()
{
    int i, j, k, score = 0;
    char ch;
    int a[ROW][COL] = {0};
    int speed = 300;

    while (1) {
        system("cls");
        for (i = ROW - 1; i >= 0; i--) {
            for (j = 0; j < COL; j++) {
                if (a[i][j] == 1) {
                    printf("■");
                } else {
                    printf("  ");
                }
            }
            printf("\n");
        }

        if (kbhit()) {
            ch = getch();
            if (ch == 'a') {
                for (i = ROW - 1; i >= 0; i--) {
                    for (j = 0; j < COL - 1; j++) {
                        a[i][j] = a[i][j + 1];
                    }
                    a[i][COL - 1] = 0;
                }
                a[ROW - 1][rand() % COL] = 1;
            }
        } else {
            for (i = ROW - 1; i >= 1; i--) {
                for (j = 0; j < COL; j++) {
                    a[i][j] = a[i - 1][j];
                }
            }
            for (j = 0; j < COL; j++) {
                a[0][j] = 0;
            }
            a[0][rand() % COL] = 1;
        }

        for (k = 0; k < score / 10; k++) {
            speed -= 10;
        }
        Sleep(speed);

        for (j = 0; j < COL; j++) {
            if (a[ROW - 1][j] == 1) {
                printf("Game Over! Your score is %d.\n", score);
                system("pause");
                return 0;
            }
        }
        score++;
    }

    return 0;
}
