I am able to type blank space and write everything into the client.
However one last problem.
When the user enter a country lets say China, It will returned everything I write but the terminal just hanged there and I can't type anything even there is a loop to ask user enter again.
I know there is something on at the readOutput function but I dunno where it go wrong

User enter input in the client and readOutput will show what the server has wrote

Client side
Code:
while(1){

   int ret;
   char country[300];
   printf("2) To end program, type 'end'\n\n\n");
   printf("Please enter country name > ");
   scanf("%[^\n]s",country);
   if (strcmp(country, "end") == 0)
   break;
   else
   write(clientFd,country,strlen(country));
   readOutput (clientFd); 
   }
   close (clientFd); /* Close the socket */
   exit (/* EXIT_SUCCESS */ 0); /* Done */

 }

function readOutput in client
Code:
readOutput (fd)

 int fd;

 {

   char str[200];
    while (readLine (fd, str)) /* Read lines until end-of-input */
     printf ("%s\n", str); /* Echo line from socket */	

 }

function readLine in client side
Code:
readLine (fd, str)

 int fd;

 char* str;



 /* Read a single NULL-terminated line */



 {

   int n;

   do /* Read characters until NULL or end-of-input */

     {

       n = read (fd,str, 1); /* Read one character */

     }

   while (n > 0 && *str++ != 0);

   return (n > 0); /* Return false if end-of-input */

 }
