[harry potter] why did snape never tell dumbledore where voldemort was hiding?

 when snape became a spy, why did he never tell dumbledore where voldemort's hideout was? I guarantee that if he had told, Harry would not have been an orphan.

Just because you know where a hideout is, doesn't mean you can take it out.
Voldemort's base was likely guarded with all sorts of horrific protection spells and enchantments which would seriously wound/kill/torture any who tried to enter it. And this is assuming that Voldemort didn't also use the fidelius charm or something similar to prevent his cronies from betraying his location.

Furthermore, Dumbledore and Voldemort are on equal standing more or less. As such, if Dumbledore was to fight Voldemort in the place most favourable to Voldemort, then Dumbledore would be lucky to leave alive.
