这里dwvalue1:31,表示占32个bit中的31位,而dwvalue2:1,表示占32个bit中的最低位bit。这样这两个成员变量总共只占一个双字节32bit。这样写的往往用来网络字节编程中,比如ip/tcp等的包头的字段定义,可以节省字节。比如ip包头的版本就只占几个bit,就是这样写的。
4. Given the declarations struct ListNode { float volume; ListNode* next; }; ListNode* headPtr; assume that headPtr is the external pointer to a linked list of many nodes. Which statement deletes the first node? ...
