A pointer to 2d array

Question

I have a question about a pointer to 2d array. If an array is something like

int a[2][3];

then, is this a pointer to array a?<

Answer 1

you can point to 2d array like 1d array

#include 
int main()
{
   int array[2][2] = {{0,1}, {2,3}}; // array
   int *ptr;
   ptr=(int*)array;
   std::cout << *(ptr)   << '\n';//out 0
   std::cout << *(ptr+1) << '\n';//out 1 
   std::cout << *(ptr+2) << '\n';//out 2
   std::cout << *(ptr+3) << '\n';//out 3
}
