Chapter 1. Object Lessons

In C, a data abstraction and the operations that perform on it are declared separately—that is, there is no language-supported relationship between data and functions. We speak of this method of programming as procedural, driven by a set of algorithms divided into task-oriented functions operating on shared, external data. For example, if we declare a struct Point3d, such as the following:

typedef struct point3d 
{ 
   float x; 
   float y; 
   float z; 
} Point3d;
