Question
Overall, how many bits in this structure definition will be used out of the overall structure allocation (as compared to how many are unused or used as padding)?Struct example { uint16_t a:2 uint16_t b:3 uint16_t c:4 uint16_t d;};1 point64 bits are being used32 bits are being used25 bits are being used10 bits are being used7 bits are being used
Solution
The structure definition includes the following:
uint16_t a:2uses 2 bitsuint16_t b:3uses 3 bitsuint16_t c:4uses 4 bitsuint16_t d;uses 16 bits (since uint16_t is a 16-bit unsigned integer)
Adding these up, we get a total of 2 + 3 + 4 + 16 = 25 bits being used.
So, the answer is "25 bits are being used".
