| Jul 4, 2016 at 7:27 | comment | added | Domas Kalinauskas | I've taken another look at your comment and the tip giving greedy walkthrough and figured out the problem. I was not rounding it properly. All I needed to do when converting to an int is to also include the round in the same command. | |

When you add all those coins together, what's the total? Try printing out change immediately after int change = changefloat * 100;

It says it uses 22 instead of 18 and I have no idea what's wrong. I did add some parts to the code so it tells me how much it uses of a specific coin and instead of using 16 of 25 and 2 of 10 it uses 16 of 25, 1 of 10, 1 of 5 and 4 of 1. Any hints at how to fix this? edit: updated code in the top post thingy | |
