| |
| <code>//Declares Integer 'dooff' and sets to Zero"
| |
| int doreload=0, dooff=0;</code><br>
| |
| <br>
| |
| Correct:<br>
| |
| <code>//dooff(Do Off) is a flag that tells the program to quit looping and properly shuts down the wii
| |
| int dooff=0;</code><br>

| <!--Sorry about the many !unsure! things, I am at work and doing this during lunch. I will have more time tonight to confirm 100% each function and provide a good explanation. -->
