5.请指出下面代码的错误 int handle_message(int message_id) { int result = 0; switch (message_id) { case MSG_ ID_NOTIFY: route_to_notify_thread (message_id); break; case MSG_ID_SHUTDOWN: case MSG_ID_REBOOT: LOGI("System Message %d =====\n", message_id) send_msg_to_sys_thread(message_id); break; default: LOGE ("===== Kaka Wrone Message %d =======\n", message_id) break; } return result;

下面代码的错误是在两个case语句中缺少了break语句，导致程序会继续执行下一个case语句的代码。正确的代码如下：

int handle_message(int message_id) {
    int result = 0;
    switch (message_id) {
        case MSG_ID_NOTIFY:
            route_to_notify_thread(message_id);
            break;
        case MSG_ID_SHUTDOWN:
        case MSG_ID_REBOOT:
            LOGI("System Message %d =====\n", message_id);
            send_msg_to_sys_thread(message_id);
            break;
        default:
            LOGE("===== Kaka Wrone Message %d =======\n", message_id);
            break;
    }
    return result;
}
