怎么显示枚举类型呢？请求帮助，谢谢！

[解决办法]
1、枚举输入输出的时候以整型来描述；
2、recvbuf.xb是不对的，因为recvbuf只是一个char数组，没有域的概念，不能用.只能用[]来取值。
[解决办法]
如果你想用字符型表示性别就不用定义枚举类型了
typedef char gender;
[解决办法]
//recvfrom(sockfd, recvbuf, MAXSIZE, 0, (struct sockaddr*)&client_addr, &client_addr_len);
recvfrom(sockfd, (char*)&stu, MAXSIZE, 0, (struct sockaddr*)&client_addr, &client_addr_len);
