Chapter 3

1. This depends on the CPU architecture. On some CPUs, a short int is 16 bits wide, while an int is 32 bits wide. This is not the case on all CPUs.
2. This depends on the CPU architecture. On most CPUs, an int is 32 bits wide, but this is not always the case.
3. No.
4. An int32_t will always be 32 bits wide. On some CPUs, an int could be 16, 32, or 64 bits wide.
5. Yes. These are called exact-width types and will always be the desired width.
6. Ensures that structures are not automatically padded by the compiler for optimizations.
7. No.
