You will be delighted by the C++11 range-based for loop:

for(auto i : whateverSTL)
{
  // here you have all the element of the container as i, one at a time

}


no need for template, just basic code.

Real software engineers work from 9 to 5, because that is
the way the job is described in the formal spec.  Working
late would feel like using an undocumented external procedure.
