基於Tcp實現簡單網絡英譯漢功能

這裏就實現簡單英譯漢的功能（手動翻譯嘻嘻嘻嘻,勿怪），既然需要把單詞和翻譯一一對應起來，這裏就可以接需要借用map容器。搭建服務器端與客戶端，然後讓其進行通信（這裏用Tcp）。
接下來就直接上代碼：
服務端：Server.cc

#include<iostream>
#include<map>
#include<unistd.h>
#include<string>
#include<sys/types.h>
#include<sys/socket.h>
#include<stdlib.h>
#include<arpa/inet.h>
using namespace std;
map<string,string>m;//{{"apple","蘋果"},{"banana","香蕉"},{"orange","橙子"},{"grape","葡萄"}};
void ServerIO(int sock)
{ 
   while(1)
   {
   char word[1024];
   string result;
   int ret1= recv(sock,word,sizeof(word),0);
   if(ret1<0)
   {
   cerr<<"recv fail..."<<endl;
   exit(6);
   }
   else if(ret1==0)
   {
   cerr<<"Client Close..."<<endl;
   break;
   }
   else
   {//success
       string s(word);
   if(m.find(s)==m.end())
   {
   result="Unknow";
   }
   else
       result=(m.find(s))->second;
   send(sock,result.c_str(),sizeof(result),0);
   }
   }
   close(sock);
}
int main()
{

    m.insert(make_pair("apple","蘋果"));
    m.insert(make_pair("banana","香蕉"));
    m.insert(make_pair("orange","橙子"));
    m.insert(make_pair("grape","葡萄"));
    int sock=socket(AF_INET,SOCK_STREAM,0);
    if(sock<0)
    {
    cerr<<"socket fail..."<<endl;
    exit(1);
    }
    struct sockaddr_in local;
    local.sin_family=AF_INET;
    local.sin_addr.s_addr=htonl(INADDR_ANY);
    local.sin_port=htons(8080);
    socklen_t len1=sizeof(local);
    int num1=bind(sock,(struct sockaddr *)&local,len1);
    if(num1<0)
    {
    cerr<<"bind fail..."<<endl;
    exit(2);
    }
    int num2=listen(sock,6);
    if(num2<0)
    {
    cerr<<"listen fail..."<<endl;
    exit(3);
    }
    while(1)
    {
    struct sockaddr_in peer;
    socklen_t len2=sizeof(peer);
    int onesock=accept(sock,(struct sockaddr *)&peer,&len2);
    if(onesock<0)
    continue;
    cout<<"Get a new line..."<<endl;
    ServerIO(onesock);
    }
    close(sock);
    return 0;
}

客戶端：Client.cc

#include<iostream>
#include<map>
#include<unistd.h>
#include<string>
#include<sys/types.h>
#include<sys/socket.h>
#include<stdlib.h>
#include<arpa/inet.h>
using namespace std;
int main()
{
    int sock=socket(AF_INET,SOCK_STREAM,0);
    if(sock<0)
    {
    cerr<<"socket fail..."<<endl;
    exit(1);
    }
    struct sockaddr_in local;
    local.sin_family=AF_INET;
    local.sin_addr.s_addr=inet_addr("127.0.0.1");
    local.sin_port=htons(8080);
    int len=sizeof(local);
    int ret=connect(sock,(struct sockaddr*)&local,len);
    if(ret<0)
    {
    cerr<<"connect fail..."<<endl;
    exit(2);
    }
    while(1)
    {
    string mas;
    cout<<"Please into word: ";
    cin>>mas;
    int ret2=send(sock,(void *)mas.c_str(),sizeof(mas),0);
    if(ret2<0)
    {
    cerr<<"send fail..."<<endl;
    exit(3);
    }
    char result[1024];
    int ret3=recv(sock,result,sizeof(result),0);
    if(ret3<0)
    {
    cerr<<"recv fail..."<<endl;
    exit(4);
    }
    cout<<result<<endl;
    }
    close(sock);
    return 0;
}

我是在Linux下寫的，運行結果如下圖：左邊服務器端，右邊客戶端。
