    input data from a website.

    Hi all,

    I am trying to write a program that will extract data from a web site. And out put it to a file, previously I have used piping to input/output data, but I though it was time I learnt another method, with to me seems much more effective. But where I have hit a brick wall is that I want it to loop and every time I want it to increment the url by 1. I had a stab in the dark as how to do it, but it wont work. Any one able to tell me where I am going wrong?
    sorry if i am not that clear, but hopefully the code i have posted below clears every thing up.
    Code:
    #include <iostream>
    #include <fstream>
    using namespace std;
    
    int main ()
    {
        ofstream siteHTML;
        for (int i=0; i<100; i++)
        {
            siteHTML.open("http://website.com/page.php?u="i, iso::in);
        }
        return 0;
    }

    Which OS/Compiler?

    For Linux (or indeed windows), look at http://curl.haxx.se/

    For Windows only, search the windows board as this was discussed pretty recently.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.
