      My linking problem is resolved.. thanks to you.. but now i am having another problem..
      why my code is not creating the socket... the descriptor is always -1..!!

      #include "stdafx.h"
#include <iostream>
#include <conio.h>	
#include <winsock2.h>
using namespace std;
int main()
{
	int descriptor;

	if ((descriptor = socket(PF_INET,

              <div> vs <table>

              I am working in html and find <div>very helpful..
              My question is, should I stop using table anymore to structure html contents or for any purpose as everything that can be done with table can be done more efficiently with div?

                replied to Why write return 0 at the end?
                in C
                I couldn't understand this (not getting the technical terms like command line program.!):
                they run a command line program in a debug from there IDE. When run this way when the program exits the Window closes so they put in the getch so the program doesn't exit. If run not in debug mode or directly from Windows or from a command prompt, as a command line program is intended to be run, then the results remain on screen.

                  Why write return 0 at the end?

                  Code:
                  #include <iostream.h>
#include <conio.h>
int main ()
{
    cout << "Hello World";
    getch();
    return 0;
}
                  In the above code, why is it necessary to write getch() and return 0? What is their purpose?

                      What do you mean by explicitly calling delete and no, it did not crash!

                        What is the actual concept of delete operator?

                        Hello all. I am c++ beginner. I am not getting the real concept of delete operator. If it deallocates the memory, then why i am getting such output..!!


                        Code:
                        int main()
{
    int *a , b=5;
    a = & b;
    cout << *a << endl;
    delete a;
    cout << *a;
    getch();
    return 0;   
}
                        Output:
                        5
                        5
