[Solved] Way to cycle through address array and see the last used? (not last assigned)

user16354157 Asks: Way to cycle through address array and see the last used? (not last assigned)
Say you have a function that repeats everyday and picks the next address on the array each time. What would be the easiest way to do this?

Example:

Code:
address[] currentAddresses;
uint lastAddress;

function Next () public returns (address) {
if (lastAddress == 1) {
   currentAddresses[2];
   lastAddress+1;

returns (currentAddresses[2]);

Having it check the last address or round and then choose the next in the array.
