I have problem extracting a substring from a input. The input consists of &nbsp;ipaddress_url_date where each underscore character indicates a space.<br />
I am using:<br />
&gt;&gt;procStr=ip.substr(ip.fin<wbr />d_first_of<wbr />(&quot; &quot;), ip.find_last_of(&quot; &quot;));<br />
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?

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
