Oct 30, 2011 at 3:00	comment	added	smerlin		you can either store the `std::string` returned by gettitle() in a named std::string variable, or pass the `const char*` returned by c_str() directly to `strcmp`. If gettitle() returns a `std::string&` or a `const std::string&`, the old code was fine.
Oct 30, 2011 at 3:00	comment	added	Mysticial		The reason is this: If a temporary is returned. It is destroyed after the statement ends. At which the pointer returned by `c_str()` is no longer valid. I have updated my answer to address this issue.

Oct 30, 2011 at 2:56	comment	added	user618879		thanks that took care of that part. didnt know i needed to put .c_str() at the end
Oct 30, 2011 at 2:56	comment	added	smerlin		u dont know if gettitle() returns a temporal string object, if that's the case, this code will yield undefined behaviour when trying to use `c_str`
