tcp server client communication read() write() problems. c language

I have problem, i write a tcp client in c but problem is that client send
command to server server send response to that command, response is
xxx#.But in client when i read from socket i read 2 response from server
for example xxx#xxx#.know client send response only for first response
form server and one response is delete.this is not the same all the time
for example client may read only 1 response ind will response to that.HOW
TO SEARCH FOR # in char array and to extract commands and client response
to all response from server.Any ideas?
i have idea for one write from client to server to read response in client
is that good idea or i write to server and in one read i read all
response?
