{solved} Need help with this output - C language

Question

What is the output of this code?
(assuming 8 byte pointers)
const char firstname[] = "dev";
const char* lastname = "programmer";

printf("%lu\n", sizeof(firstname) + sizeof(lastname));

Edit:

I am not sure of this but for dev it can be
3 char each of 1byte + one \0 of 1 byte so the size is 4

Answer 1

Answer 2

Coder Kitten My bad since sizeof operator has the firstname passed to it i assumed it would output the char ptr size and not the array size

this was interesting!
