Question

Is there a way to get the equality operators to work for comparing arrays of the same type?

For example:

int x[4] = {1,2,3,4};
int y[4] = {1,2,3,4};
int z[4] = {1,2,3,5};
if (x == y) cout << "It worked!"

I’m aware that as is, it’s just comparing pointer values – but I was hoping there’s some kind of typedef trick or something like that so it wouldn’t need a loop or a memcmp call.

You can use the standard std::equal algorithm (or std::ranges::equal since C++20):

if (std::equal(x, std::end(x), y)) cout << "It worked!";
// or since C++20
if (std::ranges::equal(x, y)) cout << "It worked!";
