Initialiser list passed as function parameter for array

Question

How do I make this work:

void foo(uint8_t a[]) { ... }

foo({0x01, 0x02, 0x03});

It gives me an error:

error: cannot conver         


        

Answer 1

You cannot. Just construct

uint8_t a[] = {0x01, 0x02, 0x03};

and call foo(a).

Or just use std::array, that is probably better.
