Re: [Boost-users] Does boost have something like this, or does it need one?

I need something like this:
template <typename Type>
struct Array;
But I think boost doesn't have it. boost::array also takes an std::size_t
template parameter but that doesn't work for what I want to do because
I want to be able to pass a function something like this:
void myFunction(const Array<int> &a) { ... }
void main()
{
int myVec1[6] = { 1,2,3,4,5,6 };
  int myVec2[2] = { 7,8 };
myFunction(Array<int>(myVec1, 6));
  myFunction(Array<int>(myVec2, 2));
}
I can't do this with boost::array and std::vector allocates and I don't want 
that too. Any help?
You can use iterator_range.

#include 
#include <iostream>
#include <algorithm>

typedef boost::iterator_range int_array;

void myFunction(const int_array &a) {
    std::copy(a.begin(), a.end(), std::ostream_iterator<int>(std::cout, 
" "));
}

int main() {
     int myVec1[6] = { 1,2,3,4,5,6 };
     int myVec2[2] = { 7,8 };

     myFunction(int_array(myVec1, myVec1 + 6));
     myFunction(int_array(myVec2, myVec2 + 2));
}
