These need to match up, but they don't. Since the <code>(</code> before the second <code>strlen()</code> is superfluous (there is no need to wrap <code>strlen(ss.str)</code> in brackets), you can remove it.</p> <p><a href="http://ideone.com/4e2Bh" rel="nofollow noreferrer">Original code with changes to the <code>#include</code>s</a> and <a href="http://ideone.com/gCPxh" rel="nofollow noreferrer">fixed code</a>. Note that I had to change the <code>#include</code>s from <code>string.h</code> to <code>cstring</code> for ideone. It's the preferred choice anyway. I also had to add <code>using namespace std;</code> as your code wasn't explicitly using the <code>std</code> namepsace where required, e.g. using <code>cout</code>. You should also <a href="https://stackoverflow.com/questions/59670/how-to-get-rid-of-deprecated-conversion-from-string-constant-to-char-warning">take care of those warnings</a>.</p> <p>The reason the compiler error points to 4 lines down is because that's the line where it realises "Oh no, there's a problem here I'm never going to be able to parse this code!" GCC is pretty crappy at error reporting, but a but a compiler (e.g. clang) that does a better job of it would backtrack to the appropriate line where the root cause of the error actually lies and may even suggest a fix for you.</p>
