Easy but weird

I have problem extracting a substring from a input. The input consists of  ipaddress_url_date where each underscore character indicates a space.
I am using:
>>procStr=ip.substr(ip.find_first_of(" "), ip.find_last_of(" "));
to extract url from the input but it does not work and procStr ends up with url_date thought I am just trying to extract url. Whats wrong?

Try with this:
     // test string  
     ip = " http://www.yoursite.com 10/02/2004";
    size_t pos=ip.find_first_of(' ') +1;
   procStr=ip.substr(pos, ip.find_last_of(' ')-pos);

    cout << procStr << endl;

You have to notices that second argument of substr() is not a position, but a character count.

Good luck,
