Question about storing array in a std::vector in C++

Question

I am unclear about the following.

First, this code compiles fine:

#include 

typedef struct{
    int x1,x2,x3,x4;
}  ints;

typedef std

It's been a little while since I used C++, but I believe the core problem you're encountering is that arrays don't have the required semantics to get along well with a std::vector<>. I don't have my copy of Stroustrup handy, or I'd give you a reference.
