Character Array initialization

Question

I'm currently playing a bit with C and trying to understand strings. Can somebody please explain why this is working:

char test[] = "test";

And why the following does not?

char test[255];
test = "test";

Answer 1

Because this is an initialization:

char test[] = "test";

and this is an assignment:

test = "test";

and you cannot assign arrays in C (and strings in C are just arrays).

Your best bet is to copy the string using strcpy() (or to be safe, strncpy()).
