0 x 27

6. If the declaration unsigned c:5; is replaced by unsigned : 6; then

it results in a syntax error

it is meaningless

compiler will give a new name for the field

none of these

repeated execution may result in different addresses for i

i may not have an associated address

263

ASCII equivalent of 263

rings the bell

garbage
