Problème projet informatique industrielle

Bonjour,
J'ai un projet informatique à effectuer pour la fin de l'année et j'ai déja bien avancé mais mon code ne plait pas au prof pcq c mal foutu. Il faudrait des classes, un tableau à double dimension et récupérer les données dans des structures.
Malheureusement je ne suis pas un pro en prog alors je galère.
Voila mon code :

/********************************************************************/

/* Communication et Récupération des données */
/*********************************************a***********************/

#include <stddef.h>
#include <stdio.h>
#include <errno.h>
#include <stdlib.h>
#include <math.h>
#include <winsock2.h>
#include <iostream>
#include<string>
#include <cstdlib>
#include <fstream>
//#include <fstream>

using namespace std;

#define TAILLE_BUF 100
#define REVEIL_OK 1
#define ESSAI_MAX 12
#define SERVER_PORT_NUM 10001 /* server's port number for bind() */
#define NBRDATA 10
#define SERVER_PORT_NUM1 20
#define SERVER_PORT_NUM2 21
#define SERVER_PORT_BIND 5000
