70. static_assert

Question.7

A developer writes a static_assert with a vague message:

static_assert(sizeof(Frame) == 8, "Error");

Another writes a descriptive one:

static_assert(sizeof(Frame) == 8,
   "CAN frame struct has padding. Expected 8 bytes for standard CAN. "
   "Use __attribute__((packed)) or reorder members.");

Which is better practice?

Both are equally useful -- the error stops compilation either way
The descriptive message is better -- it tells the developer exactly what is wrong and how to fix it, saving debugging time
The short message is better -- less code clutter
The message does not matter -- developers always check sizeof manually
