C++ File Input to Vector

Well /prog/ I'm trying to read a text file line-by-line into a vector. Is there some sort of inherent vector size limitation I don't know about?

Protip: The file has 23,000 lines. :S

(I've tested it by trying to output the first 1 or 2 vector elements after the loop, but shit just breaks because there's nothing in it??)

The pause message shows up almost instantaneously. (Text file line parsing is extremely fast regardless, in comparison to something like a URL download to file)

Because it only loops until there aren't any more lines to read from the text file
