What is the output of this program? #include #include #include #include #include int main() { int fd_server, fd_client, len, len_client; struct sockaddr_in add_server, add_client; char buff[10]; fd_server = socket(AF_INET,SOCK_STREAM,0); if (fd_server == -1) { perror("fd_sock"); exit(1); } len = sizeof(add_server); len_client = sizeof(add_client); if( bind(fd_server,(struct sockaddr*)&add_server,len) != 0) perror("bind"); fd_client = accept(fd_server,(struct sockaddr*)&add_client,len_client); if(fd_client == -1) perror("accept"); read(fd_client,buff,10); return 0; }
