哪位懂的人看看，不难

从value中变量中解析出8个阀门的当前状态，并依次输出agysushhsusuwhshsuusjzhzhxb0

bool isValueOn(unsigned char v, int iNumber)
{
    return (v & (1 << iNumber));
}

int main()
{
    unsigned char v = 0x45;
    for (int i = 0; i < 8; i++)
        printf("%d:%s\n", i, (isValueOn(v, i)) ? "On" : "Off");

    return 0;
}
