Hello. I was playing around with my new topcoder.com account, on some of the practice problems. I was trying to convert an integer to a char*/string. So, I tried to use #include <cstdlib> and itoa(...); this didn''t work so I tried and _itoa(...); and all 4 combinations. I was wondering why it kept telling me that it was undeclared. I always thought that and itoa(...); was perfectly valid. Is their something I''m missing here? Thanks in advance.

It''s not.

use snprintf

use stringstreams:
string inttostring(int i){ostringstream out;out < < i;return out.str();}int stringtoint(string s){istringstream in(s);int i;in > > i;return i;}
