Chapter 12. Storage Classes, Linkage, and Memory Management
You will learn about the following in this chapter:
auto, extern, static
register, const, volatile
rand(), srand(), time(), malloc(), calloc(), free()
How C allows you to determine the scope of a variable (how widely known it is) and the lifetime of a variable (how long it remains in existence)
Designing more complex programs
One of C's strengths is that it enables you to control a program's fine points. C's memory management system exemplifies that control by letting you determine which functions know which variables and for how long a variable persists in a program. Using memory storage is one more element of program design.
