Range-based for loop on a dynamic array?

Question

There is a range-based for loop with the syntax:

for(auto& i : array)

It works with constant arrays but not with pointer based dynamic

Answer 1

You can't use range-for-loop with dynamically allocated arrays, since compiler can't deduce begin and end of this array. You should always use containers instead of it, for example std::vector.

std::vector v(size);
for(const auto& elem: v)
    // do something
