Use the auto keyword in C++ STL

Question

I have seen code which use vector,

vectors;
s.push_back(11);
s.push_back(22);
s.push_back(33);
s.push_back(55);
for (vector::iterator i         


        

Answer 1

auto keyword is intended to use in such situation, it is absolutely safe. But unfortunately it available only in C++0x so you will have portability issues with it.
