Pushing an array into a vector

Question

I\'ve a 2d array, say A[2][3]={{1,2,3},{4,5,6}}; and I want to push it into a 2D vector(vector of vectors). I know you can use two for loops to pus

Answer 1

You can use vector::assign (pointers to array elements are valid iterators):

int a[2][3] = {{1, 2, 3}, {4, 5, 6}};
std::vector<std::vector<int> > v(2);
for (size_t i = 0; i < 2; ++i)
   v[i].assign(a[i], a[i] + 3);

Answer 2

Hm... I can produce a partial answer but not a full one.

int elementCount = 6; // I wonder if this can be done somehow with sizeof(A) * sizeof(A[0])
int* end = A + elementCount;
for(int* current = A; current < end; ++current) {
    myvector.pushback(*current);
}
