Question

The function of __attribute__((packed)); can also be performed using _________

(a) #pragma pack(1);

(b) #pragma pack(2);

(c) #pragma pack(4);

(d) #pragma pack(8);

Answer 1

The correct answer is (a) #pragma pack(1);

The best I can explain: __attribute((packed)); and #pragma(1) are used to perform the same function, that is, to direct the compiler to pack the structure.
