I dont get that error you specify?

However, what I did find was this...

Line 37 your using i which is not initialised, and its position doesn't make any sense?

Line 61 you are testing smallest_index, again its not initialised.

Sounds line you selected a WIN32 project rather than a console project.

Ah, good point AbstractionAnon, i just pasted his code into a project I created on auto-pilot, never even gave that a thought :)
