Question

Why is it not worthwhile to create a 1-bit-long data member in a 32-bit-aligned structure?

a.

It would take up too much memory

b.

It would not be readable

c.

It would require unaligned memory accesses and shifting to access

d.

None of the above

Posted under Reverse Engineering

Answer: (c).It would require unaligned memory accesses and shifting to access Explanation:Creating a 1-bit-long data member in a 32-bit-aligned structure would require unaligned memory accesses and quite a bit of shifting and ANDing to access, which would incur a significant performance penalty.
