Range-based for loop

- [Bill] Beginning with the C++11 version of C++,…there's a new range-based for loop.…This gives C++ a simple way…of iterating over the elements of a container,…an operation that used to take a bit more code.…So here in Xcode, I've left open our for.cpp…from the previous lesson,…and here, I'm actually going to change this…and make this back into our integer array.…

And down here, we're going to iterate through this array…with a range-based for loop.…So, it goes like this for…int i…in array,…and we have that colon there,…which tells us that we're iterating through a container…and the container's the right of the colon…and what each element of the container is going to be put in…is the left of the colon,…and so, each element of the array…will be placed in this integer i…during the for loop,…and so, I can simply say printf…i…is…%d…for an integer,…like that.…

And when I build and run,…you notice we get i as one, two, three, four, and five.…Now, our range-based for loop…is a compiled time feature,…and so, even though this is a simple c array…
