This is my first program apart from the infamous "HelloWorld" one. The purpose of this program is to simulate a lottery number generator. The program is printing numbers which is great, but it isn't behaving like how it should. It's supposed to print 100 number combinations and it only prints 1 to approximately 8-10. It looks like it's stuck in a loop somewhere? Also, I'm not sure if my syntax is correct in relation to the "breaks" on the loops and so forth. Lastly, when I run it in the CMD prompt the cursor doesn't go back to the C:\ root after the program has executed. Again, this is why I think it's stuck in a loop. Any comments will be much appreciated.

* If it works correctly it should automatically display 100 number combinations.
