(C++) Copying Arrays

Question

If I make an array, what's the easiest way to make an exact copy of that array?

Answer 1

I would also do @0xDEADBEEF solution but with a slit change :
Remove #include <iterator>
std::copy(arr,arr + 3,arr2); //copy arr in arr2

Answer 2

#include <algorithm>
#include <iterator>

int main() {
int arr[] = {1, 2, 3};
int arr2[3];

std::copy(std::begin(arr), std::end(arr), std::begin(arr2));

}

Answer 3

@Baptiste I use iterators usually so that in case I decide to change the array for example to a vector, I don't have to change as much code :)
