Data Hiding in C

March 2nd, 2008

Object-oriented programming languages are described as supporting encapsulation, polymorphism, and data hiding. They provide powerful features that allow software components to be designed and implemented for change. Observing the mechanisms in an object-oriented programming language can potentially lead to a parallel implementation in a procedural language. This allows some object-oriented design knowledge that has been […]

Functions, Parameters, and Global Variables in C

February 4th, 2008

When I define interfaces to the functions that I implement, I try to be explicit about the variables that the functions will examine and modify. From time to time, a global variable is necessary, and I typically employ intermediary functions for accessing such a variable. Avoiding the direct use of global variables within functions is […]
