为什么vs提示swith后面加“；”

```c

int main(void)
{
    int day = 0;
    scanf("%d", &day);
    swith(day)
    {
        case 1:
            printf("%d", 1);
            break;
        case 2:
            printf("%d", 2);
            break;
        case 3:
            ; printf("%d", 3);
            break;
    }
    return 0;

}

```

单词写错了，swith 的正确写法是switch
