segmentation fault

hi, while receiving a http request from client, Segmenation fault error is there.
Following is code:

Code:

#include<iostream>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <stdlib.h>
#include <unistd.h>
#include <errno.h>
#include <string.h>
using namespace std;
int main()
{       
	int sock, connected, bytes_recieved;        
	char recv_data[1024];        
	struct sockaddr_in server_addr,client_addr;            
	socklen_t sin_size;      
	if ((sock = socket(AF_INET, SOCK_STREAM, 0)) == -1)	
	{            
		cout<<"Socket Error Reason:"<<strerror(errno);            
		exit(1);        
	}        
	server_addr.sin_family = AF_INET;          
	server_addr.sin_port = htons(8081);        
	server_addr.sin_addr.s_addr = INADDR_ANY;       
	bzero(&(server_addr.sin_zero),8);     
	if (bind(sock, (struct sockaddr *)&server_addr, sizeof(struct sockaddr))== -1)	
	{            
		cout<<"Unable to bind: Reason="<<strerror(errno);           
		exit(1);      
	}     
	if (listen(sock, 5) == -1) 
	{          
	cout<<"Listening error: Reason="<<strerror(errno);          
	exit(1);       
	}			
	cout<<"\nTCPServer Waiting for client on port 8081";       
	cin.sync(); 	
	sin_size = sizeof(struct sockaddr_in);        
	connected = accept(sock, (struct sockaddr *)&client_addr,&sin_size);        
	cout<<"\n Server got a connection from "<<ntohs(client_addr.sin_port)<<endl;
	bytes_recieved = recv(connected,recv_data,1024,0);        
	recv_data[bytes_recieved] = '\0';	
	if((bytes_recieved==0)||(strcmp(recv_data,"\0")==0))
	{		
		close(connected);			
	}	
	else	
		cout<<"\n RECIEVED DATA = "<<recv_data;              
	cin.sync();
	shutdown(sock,2);
	close(sock);
	return 0;
}

Please help.

Time to learn how to use the debugger then.

Code:

g++ -g prog.cpp
gdb ./a.out
<< snipped gdb banner
(gdb) run

gdb will catch the segfault, and allow you to look around your code to see what went wrong.
Examine variables around the fault location to make sure they have values you expect.

Think you might like

Code:

recv_data[0] == '\0'

better than

Code:

(strcmp(recv_data,"\0")==0)
