C++ socket code

Sorry, as an AI language model, I cannot provide you with a complete code without knowing the specific requirements of your project. However, I can give you a basic example of a client-server communication code using sockets in C.

Server Side:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>

int main(){
    int server_socket, client_socket, port_number;
    socklen_t client_length;
    char buffer[256];

    struct sockaddr_in server_address, client_address;

    // create socket
    server_socket = socket(AF_INET, SOCK_STREAM, 0);
    if (server_socket < 0) {
        perror("Error opening socket");
        exit(1);
    }

    // initialize server address
    bzero((char*) &server_address, sizeof(server_address));
    port_number = 8080;
    server_address.sin_family = AF_INET;
    server_address.sin_addr.s_addr = INADDR_ANY;
    server_address.sin_port = htons(port_number);

    // bind socket to address
    if (bind(server_socket, (struct sockaddr*) &server_address, sizeof(server_address)) < 0) {
        perror("Error binding socket");
        exit(1);
    }

    // listen for incoming connections
    listen(server_socket, 5);

    // accept client connection
    client_length = sizeof(client_address);
    client_socket = accept(server_socket, (struct sockaddr*) &client_address, &client_length);
    if (client_socket < 0) {
        perror("Error accepting connection");
        exit(1);
    }

    // read message from client
    bzero(buffer, 256);
    read(client_socket, buffer, 255);
    printf("Received message from client: %s\n", buffer);

    // send response to client
    char response[] = "Hello from server!";
    write(client_socket, response, strlen(response));

    // close sockets
    close(client_socket);
    close(server_socket);

    return 0;
}

Client Side:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <netdb.h>

int main(){
    int client_socket, port_number, n;
    struct sockaddr_in server_address;
    struct hostent* server;

    char buffer[256];

    // create socket
    client_socket = socket(AF_INET, SOCK_STREAM, 0);
    if (client_socket < 0) {
        perror("Error opening socket");
        exit(1);
    }

    // get server by hostname
    server = gethostbyname("localhost");
    if (server == NULL) {
        perror("Error finding server");
        exit(1);
    }

    // initialize server address
    bzero((char*) &server_address, sizeof(server_address));
    port_number = 8080;
    server_address.sin_family = AF_INET;
    bcopy((char*) server->h_addr, (char*) &server_address.sin_addr.s_addr, server->h_length);
    server_address.sin_port = htons(port_number);

    // connect to server
    if (connect(client_socket, (struct sockaddr*) &server_address, sizeof(server_address)) < 0) {
        perror("Error connecting to server");
        exit(1);
    }

    // send message to server
    char message[] = "Hello from client!";
    write(client_socket, message, strlen(message));

    // read response from server
    bzero(buffer, 256);
    read(client_socket, buffer, 255);
    printf("Received message from server: %s\n", buffer);

    // close socket
    close(client_socket);

    return 0;
