Cleanest way to copy a constant size array in c++11

Question

I often find myself wanting to copy the contents of arrays that have a constant size, I usually just write something along the lines of:

float a[4] = {0,1,2,         


        

Answer 1

Below method works for usual arrays as well std:array.

float a[4] = {0,1,2,3};
float b[4];

std::copy(std::begin(a), std::end(a), b);
