How to fix this client-server code to print to stdout? - c

Question

I'm trying to write a client-server program in C. For now I have a connection between the server and the client but for some reason nothing happens or prints after the "connected" print.
I've tried sample printing before and after the "connected" but nothing shows on my shell.
my server:
int main(void)
{
int sockfd, newsockfd, portno, clilen;
struct sockaddr_in serv_addr, cli_addr;
sockfd = socket(AF_INET, SOCK_STREAM, 0);//Af_INet is protocol tcp np? ip? - this creates an empty socket
if (sockfd < 0)
{
printf("socket failed\n");
exit(0);
}
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &(int){ 1 }, sizeof(int)) < 0)
{
printf("setsockopt failed\n");
exit(0);
}
// calls to bind(), listen() and accept() here
memset((char *) &serv_addr, 0, sizeof(serv_addr));
portno = 8888;
serv_addr.sin_family = AF_INET;
serv_addr.sin_addr.s_addr = INADDR_ANY;
serv_addr.sin_port = htons(portno);
if (bind(sockfd, (struct sockaddr *)&serv_addr, sizeof(serv_addr)) < 0)
{
printf("bind failed\n");
exit(0);
}
listen(sockfd, 5);
clilen = sizeof(cli_addr);
newsockfd = accept(sockfd, (struct sockaddr *) &cli_addr, &clilen);
if (newsockfd < 0)
{
printf("accept failed\n");
exit(0);
}
//end calls
printf("[Server] Connected\n"); // nothing prints before or after this
int n;
char query[BUFFER_SIZE]={0};
char result[BUFFER_SIZE]={0};
char *hello = "Hello from client";
send(newsockfd, hello , strlen(hello) , 0 ); //write also doesn't work
printf("Hello message sent\n");
n = read( newsockfd, query, BUFFER_SIZE);
printf("%s\n",query );
close(newsockfd);
close(sockfd);
my client:
int main(void)
{
int sockfd, portno;
struct sockaddr_in serv_addr;
struct hostent *server;
sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd < 0)
{
printf("socket failed\n");
exit(0);
}
//get host and connect
portno = 8888;
server = gethostbyname("localhost");
if (server == NULL)
{
printf("gethostbyname failed\n");
exit(0);
}
memset((char *)&serv_addr, 0, sizeof(serv_addr));
serv_addr.sin_family = AF_INET;
memcpy((void*)&serv_addr.sin_addr.s_addr, (void*)server->h_addr, server->h_length);
serv_addr.sin_port = htons(portno);
if (connect(sockfd, (struct sockaddr *)&serv_addr, sizeof(serv_addr)) < 0)
{
printf("connect failed\n");
exit(0);
}
//end connect
printf("client here");//doesn't show on shell screen
printf("[Client] Connected\n");//shows on shell screen
int n;
char *hello = "Hello from client";
char query[BUFFER_SIZE]={0};
char result[BUFFER_SIZE]={0};
send(sockfd, hello, strlen(hello), 0);
printf("Hello message send\n");
n=read(sockfd,query,BUFFER_SIZE);
printf("%s\n",query);
close(sockfd);
I compile these with:
gcc -Werror -std=c99 server.c -o server
gcc -Werror -std=c99 client.c -o client
Also, I ran ./server before ./client , the shell screens show "Connected" on both client and server screens and that's it no matter what I write on the screen (either client's or server's)
Any help would be appreciated!
