Question

I have a class with a private data member of type vector< A*>.

The class has two public methods that actually use vector<A*>::size_type:

1. Method returning number of elements in the vector
2. Method returning element in the vector by index

I can add to public section of the class the following typedef:

typedef vector::size_type SIZE_t;

but IMHO it exposes too many details about class implementation.

Another approach is to use size_t.

What do you think?

Answer 1

Use plain old size_t for both member functions.
