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

Try boost::array instead of plain arrays. It provides STL-compliant interface around fixed-size arrays, so it can be used inside STL containers. Plus, it implements boundary checking (boost::array::at).

#include 
#include 

typedef std::vector< boost::array > vec;
int main(){
    vec v;
    boost::array va = {0,1,2,3};
    v.push_back(va);
}
