Week 3: Dynamic Data Structures (43)

An executing C program partitions memory into:

code … fixed-size, read-only region
- contains the machine code instructions for the program
global data … fixed-size
- contain global variables (read-write) and constant strings (read-only)
heap … very large, read-write region
- contains dynamic data structures created by malloc() (see later)
stack … dynamically-allocated data (function local vars)
- consists of frames, one for each currently active function
- each frame contains local variables and house-keeping info
