You're working on an embedded system with limited memory. What feature of C would you use to efficiently pack multiple flags into a single byte?
- Bit fields
- Pointers
- Inline functions
- Function pointers
Option A, "Bit fields," is the correct choice. Bit fields allow you to efficiently pack multiple boolean flags into a single byte, which is essential in resource-constrained embedded systems, helping to save memory. Bit fields provide control over the size and alignment of data within a structure, allowing you to use memory more efficiently. Other options are not typically used for this purpose and may not offer the same level of memory optimization. Bit fields are an important concept for embedded systems programming.
