Arrays and Functions

Module by: Kenneth Leroy Busbee. E-mail the author

Summary: An introduction to processing arrays with functions with an example of displaying an array within the C++ programming language.

Overview of Array Functions

Arrays are an important complex data type used in almost all programming. We continue to concentrate on simple one dimension arrays also called a list. Most programmers develop a series of user defined specific task functions that can be used with an array for normal processing. These functions are usually passed the array along with the number of elements within the array. Some of functions also pass another piece of data needed for that particular functions task.

This module covers the displaying the array members on the monitor via calling an array function dedicated to that task. You need to study this module in conjunction with the demo file provided.

Demonstration Program in C++

Creating a Folder or Sub-Folder for Source Code Files

Depending on your compiler/IDE, you should decide where to download and store source code files for processing. Prudence dictates that you create these folders as needed prior to downloading source code files. A suggested sub-folder for the Bloodshed Dev-C++ 5 compiler/IDE might be named:

  • Demo_Programs

If you have not done so, please create the folder(s) and/or sub-folder(s) as appropriate.

Download the Demo Program

Download and store the following file(s) to your storage device in the appropriate folder(s). Following the methods of your compiler/IDE, compile and run the program(s). Study the source code file(s) in conjunction with other learning materials.

Download from Connexions: Demo_Array_Display_Function.cpp
