Calculator Programming Tutorial

Programming Building Blocks I

Introduction

There are relatively few fundamental ideas on which computer programming is based. These ideas may be thought of as an alphabet of computer programming: relatively few ideas are combined in variations to form functional wholes. This section describes these ideas, and to some extent attempts to describe how they interact.

The basic ideas described in this section are:

Comments and white space
Data types
Numbers
Variables and assignment
Expressions
Control flow and control structures
Subprograms
Basic input and output
Algorithm design techniques.

In addition, this section discusses the mechanics of entering a program in each of JavaScript, Microsoft Word VBA, and the calculator, and gives a series of exercises with answers.
