## 增加功能
### 1.space
按空白鍵直接到底

case 32:
    while(isCollision(cur_x,cur_y+1)!=1)
    {
        eraseBlock(block_cur,cur_x,cur_y);
        cur_y++;
        printBlock(block_cur,cur_x,cur_y);    
    }
    break;

### 2.整版變色

        case O:
            system("color 01");
            copy_block(blockO,block_cur);
            break;
        case J:
            system("color 02");
            copy_block(blockJ,block_cur);
            break;
        .
        .
        .

七種顏色
#### 1.O

#### 2.J

#### 3.L

#### 4.I

#### 5.Z

#### 6.S

#### 7.T

### 3.分數
削掉一條+10分

    clear_line++;
    score += 10;
