Re: [Boost-users] RunTime error + lexical_cast + string with space

I noticed the below crashes[run time error because of space in string] Is there a possibility to handle this situation? [without explicitly calling split]

  string s = "   12252001";   int offsets[] = {5,2,4};   offset_separator f(offsets, offsets+3);   tokenizer tok(s,f);   for(tokenizer::iterator beg=tok.begin(); beg!=tok.end();++beg)           int val = boost::lexical_cast<int>( *beg);

You should explicitly trim every token (use boost/algorithm/string/trim.hpp). Alternatively, you could use more flexible facility, like Spirit.
