In $C++11$, you can iterate over each element in a list with less code:

== code(cpp) |

If you want to modify the elements in the list, you need to get a reference to the current element:

If you want to modify the elements in the list, you need to get a reference to the current element like this:

== code(cpp) |
double array[5] = {1.5, 2.7, 3.9};
