2.3 Memory Maps

2.4 Stacks

3.2 Variable Naming, Types and Declaration

3.3 Functions

All programs must have a place to start, and in C, program execution begins with a function called main. This does not have to be the first function written or listed, but all programs must have a function called main. Here’s our first program, found in Figure 3.2, following:

12.2 Free Memory Pool

12.3 Allocating Memory

12.4 Using Memory

Note the freedom that we have with the pointer. It can be used as a normal pointer or thought of as the base of an array and indexed accordingly. Similarly, we might need to allocate a structure and initialize its fields. Here is a function that we can call to allocate a struct foobar, initialize some fields, and return a pointer to it.
