Re: Container to map a vector of structures

I recently began using STL containers, mainly to store pointers to
structures using a vector:
std::vector <dataStruc*> vdata;

Now I have a new requirement and I need random access to each
structure contained in the vector. There will be thousands of
structures contained by my vector and I will be accessing structures
randomly multiple times--for instance, I may need to access any given
structure 10 or 20 times as I generate data for my report.

The easiest way I concieve this is to build a parallel vector that
stores the key string, such as:
std::vector <string> vKey;

Then I can 'seek' the string, obtain it's position, and using that
position, efficiently obtain the structure stored in the structure.

Would it be better to accomplish this with a different container, such
as a map or something else?
