You don't need it. It just makes the code clearer if you do. Certain classes 
of problems don't generally happen when you do that. But if someone prefers to 
not name their member variables specially, then they don't have to. Just like 
someone could prefer to always reference member variables with the this 
pointer/reference, but it's not required. Out of the two, I think that 
prepending member variables with _ makes way more sense. But to each their 
own. The language doesn't force anything on you with regards to variable names 
save for the fact that you can't use key words for them and the fact that you 
can't shadow local variables with other local variables.
