string - Check if the following position of a pointer is null or end of line C++ -

well, have iterator on string in c++

std::string::iterator itb = itc->begin();

and want check if the next position of iterator reaches end of line. i've tried this:

if(*itb ++ != null)

also this:

itb++ == itc->end()

but i'm confused , need help, since i'm rookie @ pointers in c++.

you want check without modifying it. both of attempts involve modifying itb. if have c++11, that's std::next:

std::next(itb) == itc->end()

if don't, make iterator:

std::string::iterator next = itb; ++next; next == itc->end()

although, in case know std::string::iterator random access iterator, can do:

itb + 1 == itc->end()

(the previous 2 work iterator category)
