C/C++ :: Server Receives Corrupted Data

I have a problem with this work. It is that when the server send some data to the client it send them correctly but when they arrive to the client all the info are changed and i don't know why, because i print them before the send and they are right, but after they arrive to the client the data doesn't be the same.

here it is the server and client's code. In the code there are some italian words, but there are only constant, so there is a real problem to understand the code.

Server

#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <netdb.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <stdbool.h>
#define FLUSH while(getchar()!='

[code]....

the problem is in the line 136 of the server and on the line 203 of the client
