Should I use an array in a class?

I am making a class with about 20 integers. If I make it into an array, I know it would be more complicated code, but wouldn''t it save more space and speed? Do big-name games use arrays? -Ace

vector''s are very good .
the grow exponentially though.

1 tip is to reserve your vector before using it.
Common mistake is inserting elements into a vector
without reserving it yourself..

         myvec.reserve(25); // reserve 25 blocks

this speeds up your vector ..

If you know how many elements ahead of time you want in the array, then use the ARRAY!!!!!!!!!!!!!!!!!!

The only time vectors are really needed are when you dont know how many elements/want to create more dynamically.

hmmmm
not exactly .

if you are reading records from a file, you can calculate
how many records are in the file.

but then the number of records in memory can grow.
so use a vector if you can .
