Remarks

Comparison of methods to iterate an array

Method | Advantage | —— | ——— |foreach | The simplest method to iterate an array. |foreach by reference | Simple method to iterate and change elements of an array. |for with incremental index | Allows iterating the array in a free sequence, e.g. skipping or reversing multiple elements | Internal array pointers | It is no longer necessary to use a loop (so that it can iterate once every function call, signal receive, etc.) |
