   3 mar 2010 · You want vector::size() and set::size(). Assuming v is your vector, do this: size_t size = 0; for (vector<set<char> >::const_iterator cit = v.begin(); cit != v.end(); ++cit) { size += cit->size(); } sizeof() is giving you the in-memory size of the object/type it is applied to, in multiples of sizeof(char) (usually one byte). If you want to know ...
