Weba) union b) bit-fields c) malloc d) none of the mentioned View Answer Answer: b Explanation: None. 4. For what minimum value of x in a 32-bit Linux OS would make the size of s equal to 8 bytes? struct temp { int a : 13; int b : 8; int c : x; } s; a) 4 b) 8 c) 12 d) 32 View Answer Answer: c Explanation: None. 5. WebBit fields are stored starting with the LSB. In this case, bit fields are stored in bytes (because the field type is unsigned char). So, the first byte in the union is filled with 1 (in the Least Significant 4 bits) and 2 (in the Most Significant 4 bits). WebDec 6, 2024 · It should be possible to take a C struct that includes bitfields (and other things like unnamed unions and unnamed structs), convert it to a C-compatible Rust struct, and not have to invent any new named types or new named fields.
