公共类HttpHelper扩展了AsyncTask> {ArrayList list = new ArrayList();

@Override
protected ArrayList<String> doInBackground(String... urls) {
    // TODO Auto-generated method stub

    String result="";
    for(String url:urls)
    {
        HttpClient client = new DefaultHttpClient();
        HttpGet request = new HttpGet(url);
        try

我为客户端和服务器创建了一个C程序,用于将数据从一台计算机传输到另一台计算机.以下代码

#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <stdio.h>
#include <iostream.h>

void main()
{
    int sockfd;
    struct sockaddr_in saddr;
    char *xyz,xyz1;
    sockfd = socket(AF_INET,SOCK_STREAM,0);
    saddr.sin_family = AF_INET;
    saddr.sin_port=htons(5001);
    saddr.sin_addr.s_addr = inet_aton("192.168.0.254");
    connect(sockfd,(struct sockaddr *)&saddr,sizeof(saddr));
    fgets(xyz);
    write(sockfd,xyz,sizeof(xyz));
    read(sockfd,xyz1,sizeof(xyz1));
    fputs(xyz);
    close(sockfd);
}               

但它在trubo c ++ 3.0 IDE中显示以下错误

  UNABLE TO OPEN INCLUDE FILE 'SYS/SOCKET.H'
  UNABLE TO OPEN INCLUDE FILE 'NETINET/IN.H'
  UNABLE TO OPEN INCLUDE FILE 'ARPA/INET.H'
