What if you were addressing a few female deer ? ?
no no, that would be if they owned something...
like, "Don't touch that doe's purse!"
plural for doe would be simply "doe" "look at all those doe in the field" not "look at all those does in the field". Plurals don't get apostrophes, but are used as a possessive. If you need to do both, you use a single apostrophe after the plural:
"That would be the Henrys' car"
Or, if the word in question already ends in s:
"Have you seen Bess' car", not "have you seen Besses car" Although I think pronunciation leaning towards the latter might make the sentence less ambiguous.
The apostrophe is for either contractions (to replace a letter or group of letters) or to indicate possession. It is never used to indicate a plural.
ok cbmatt , we oldie's oldies were taught to use them at the borstal school but if that is the modern or web thing thats ok 
It's not the "modern" way. you were simply taught the wrong way for some reason. Some people are taught to spell Dillema Dillemna, despite it never appearing that way in any dictionary.
edit: well this certainly has nothing to do with C++, aside from the fact that we're still talking about language. At least there is that, I suppose.
