this code is a game that uses socket to be able to connect to each other so that there would be a 2player game.. but there something wrong here...here's the code..i'm using linux as my operating system ..this is the client side..

#include <stdio.h>
#include <iostream>
//#include <conio.h>
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <netdb.h>

using namespace std;

void error(char *msg)
{
  perror(msg);
  exit(0);
}


int main(int argc, char *argv[])
{
	int  sockfd,portno, n, n1; 
	struct sockaddr_in serv_addr;
	struct hostent *server;
	
	
	char buffer[256];
	if (argc < 3) {
	   fprintf(stderr,"usage %s hostname port\n", argv[0]);
	   exit(0);
	}
	portno = atoi(argv[2]);
	sockfd = socket(AF_INET, SOCK_STREAM, 0);
	if (sockfd < 0)
	   error("ERROR opening socket");
	server = gethostbyname(argv[1]);
	if (server == NULL) {
	   fprintf(stderr,"ERROR, no such host\n");
	   exit(0);
	}
	bzero((char *) &serv_addr, sizeof(serv_addr));
	serv_addr.sin_family = AF_INET;
	bcopy((char *)server->h_addr,
	   (char *)&serv_addr.sin_addr.s_addr,
	   server->h_length);
	serv_addr.sin_port = htons(portno);
	//if (connect(sockfd,&serv_addr,sizeof(serv_addr)) < 0)
	//   error("ERROR connecting");
	//if (connect(sockfd, &serv_addr,sizeof(serv_addr)) < 0) 
        //error("ERROR connecting");	
	printf("Welcome to Battle of Jack 'en Poy\n");
	printf("Please enter your name: ");
	bzero(buffer,256);
	fgets(buffer,255,stdin);
	n = write(sockfd,buffer,strlen(buffer));
	bzero(buffer,256);
	n = write(sockfd," ! ",3);
	
	if (n < 0)
	    error("ERROR writing to socket");
	bzero(buffer,256);
	n = read(sockfd,buffer,255);
	if (n < 0)
	    error("ERROR reading from socket");
		printf("%s\n",buffer);
	return 0;

       
}

this is the server side..

you know what people...my professor didn't taught us socket..he simply game us this project..so any help would be appreciated..tnx

Are you being able to communicate from client to server ? what errors are u getting ?

"something wrong" is not a description.
There are plenty of coding errors which may be a problem in the end, but which may not be the most immediate problem.
