Learning About Range-For Loops

Use CTL-F5 to run


This little program shows how to use simple for each loops
to cycle through a collection of integers. A collection is a group of similar
objects.
In native C++ this loop is called a Ranged-For loop

I store my numbers in a vector which is a data structure that holds
multiple things much like a variable. But variables hold one value and
a vector is like a variable that can hold multiple values but all under
one name.

I also show how to sort the numbers in the vector
