Boost: Use Of Non-Dynamic Data Structures?

[Chris Gordon-Smith]

I have recently started using the Boost Graph Library(BGL);
overall I am finding it excellent and very powerful.

One thing worries me a little. It seems to be standard practice
when using BGL to create a data structure with a specific size,
and then pass a pointer (or iterator) to the start of that data
structure to an algorithm as an argument.

Is this OK? Isn't it better to dynamically allocate memory for
containers according to need, or am I missing the point?

One thing I should have made clear in the original posting: The algorithm
then populates the data structure that the argument points to. My concern
is that if the data structure was created with the wrong size, there will
be trouble.
