Enhanced for loop

Question

I can't understand about enhanced for loop
About its idea

Answer 1

If you are working with arrays and collections, you can use alternative syntax of for loop (enhanced form of for loop) to iterate through items of  arrays/collections. It is also referred as for-each loop because the loop iterates through each element of array/collection.

Answer 2

In which language?

Basically it iterates inside a collection (array, list etc) and usually performs tasks on it.

Basic foreach in c#

int[] arrayX = {1,4,5,12};

foreach (int x in arrayX) {
Console.WriteLine(x);
}

Each value inside the arrayX collection will get
1) stored inside x
2) printed using writeline
