How do I declare them and initialize depending on n?

The problem is that begin() and end() return a std::vector::iterator, whereas rbegin() and rend() return a std::vector::reverseiterator. These are different types, and your itb,ite cannot be both.

One solution is to use an intermediate function template, where the type of iterator is the template parameter. Then you can pass different types of iterators as arguments.

This is demonstrated below:

#include 
#include 
template 
void myloop(IterT const& from, IterT const& to) {
    for (IterT it = from; it != to; it++) {
        std::cout
