下面是一个面向连接的SOCKET实例，填入(n)处。
【说明】
代码实例中的服务器通过socket连接向客户端发送字符串"Hello，you are connected!"。只要在服务器上运行该服务器软件，在客户端运行客户软件，客户端就会收到该字符串。
客户端程序代码如下：
include＜stdio.h＞
include＜stdlib.h＞
include＜errno.h＞
include＜string.h＞
include＜netdb.h＞
include＜sys/types.h＞
include＜netinet/in.h＞
include＜sys/socket.h＞
define SERVPORT 3333
define MAXDATASIZE 100 /*每次最大数据传输量*/
main(int argc, char*argv[]){
int sockfd, recvbytes;
char buf[MAXDATASIZE];
stmct hostent*host;
struct sockaddr_in serv_addr;
if (1) {
fprintf(stderr, "Please enter the server's hostname!\n");
exit(1);
}
if＜(host=gethostbyname(argv[1]))=NULL) {
herror("gethostbyname出错!");
exit(1);
}
if ((sockfd = socket(AF_INET, (2), 0))=-1) {
perror("socket创建出错!");
exit(1);
}
serv_addr.sin_family=AF_INET;
serv_addr.sin_port=htons(SERVPORT);
Serv_addr.sin_addr=*((structin_addr*)host→h_addr);
bzero(&(serv_addr.sin_zero), 8);
if(connect (3), (struct sockaddr *)&serv_addr, \
sizeof(struct sockaddr))=-1) {
perror("connect出错!");
exit(1);
}
if((recvbytes=recv (4), buf, MAXDATASIZE, 0))=-1) {
perror("recv出错!");
exit(1);
}
buf[recvbytes]='\0';
pfintf("Received: %s", buf);
close(sockfd);
}
语句”Hello”．equals(”hello”)；的正确执行结果是（）。
A.true
B.false
C.0
D.1
A.cout＜＜"1."＜＜setfill('')＜＜"Hello!"＜＜endl;
B.cout＜＜"1."＜＜''＜＜"Hello! \n";
C.cout＜＜"1. Hello!"＜＜endl;
D.cofit＜＜"1."＜＜setw(7)＜＜"Hello!";
