[AJUDA] - DUVIDA Comunicação

Programação C e C++
#1

Oi,como posso fazer para o servidor e o client se comunicar,para depois adiciona um código de um placar de tenis.
Obrigada

// Client

    int sock = 0, valread; 
    struct sockaddr_in serv_addr; 
    char *hello = "Hello from client"; 
    char buffer[1024] = {0}; 
    if ((sock = socket(AF_INET, SOCK_STREAM, 0)) < 0) 
    { 
        printf("\n Socket creation error \n"); 
        return -1; 
    } 
   
    memset(&serv_addr, '0', sizeof(serv_addr)); 
   
    serv_addr.sin_family = AF_INET; 
    serv_addr.sin_port = htons(PORT); 
       
    // Convert IPv4 and IPv6 addresses from text to binary form 
    if(inet_pton(AF_INET, "127.0.0.1", &serv_addr.sin_addr)<=0)  
    { 
        printf("\nInvalid address/ Address not supported \n"); 
        return -1; 
    } 
   
    if (connect(sock, (struct sockaddr *)&serv_addr, sizeof(serv_addr)) < 0) 
    {
