| Modular Abstraction |

|
|
|
| • | With
modular abstraction, we build a “screen” |
|||||||
| surrounding
the internal structure of our program |
||||||||
| prohibiting
programmers from accessing the data |
||||||||
| except
through specified functions. |
||||||||
| • | Many
times data structures (e.g., structures) |
|||||||
| common
to a module are placed in a header files |
||||||||
| along
with prototypes (allows external |
||||||||
| references) |
