reference

Hi,

Could you please explain a little bit about vector<int>::re ference? I
know there is vector<int>::it erator. What's ::reference?

Thanks in advance,
Michael

It's a type. It's something that a non-const operator[] returns. In
most cases the 'reference' is a typedef for 'value_type&'. Just read
the source, I bet the definition of this is in your <vectorheader .
