My simple program gives no errors through the compiler and runs fine but it does not give the output it is supposed too until someone is connected. I have done a good bit of research and editing but can not figure it out.Also how do I let more than one person connect? Any help to get this to work would be appreciated. Thanks in advance!!! Code is below.
#include <iostream>
#include <sys/socket.h>
#include <arpa/inet.h>
#include <stdio.h>
#include <string.h>
char msg[20];
using namespace std;
int main(int argc, char *argv[])
{
cout << "Made it to main!";
int listener_d = socket(PF_INET, SOCK_STREAM, 0);
struct sockaddr_in name;
name.sin_family = PF_INET;
name.sin_port = (in_port_t)htons(30000);
name.sin_addr.s_addr = INADDR_ANY;
if(bind (listener_d, (struct sockaddr *) &name, sizeof(name)) == -1)
{
cout << "Can't bind the port!";
}
else
{
cout << "The port has been bound.";
}
listen(listener_d, 10);
cout << "Waiting for connection...";
while(1)
{
struct sockaddr_storage client_addr;
unsigned int address_size = sizeof(client_addr);
int connect_d = accept(listener_d, (struct sockaddr *)&client_addr, &address_size);
cin >> msg;
send(connect_d, msg, strlen(msg), 0);
}
return 0;
}

Maybe you should try flushing the output.
std::cout << "Waiting for connection..." << std::flush;
