Week 1
- Welcome!
- Went over the syllabus, formally introduced ael0 project.
- Started reviewing C by talking about pointers.
- we wrote some sample code
- pointers are a fixed size, regardless of data type
- why? MEMORY ADDRESSING
- on lab46 (running on a 64-bit OS/system), memory addresses are 64-bits (64/8 = 8 bytes)
- so all pointers (whether char, int, float, etc.) will be 8 bytes in size on this system.
- on other systems, notably 16-bit and 32-bit systems (especially late-era hardware that might have incorporated tweaks to support more memory than is typically accessible by the default machine word size), memory address sizes can vary.
- takeaway: for code portability, do not assume 8 byte memory addresses. ALWAYS use sizeof() to maximize portability.
