Basic C Programming

In this Chapter we will look at the basic aspects of C programs such as C program structure, the declaration of variables, data types and operators. We will assume knowledge of a high level language, such as PASCAL.

It is our intention to provide a quick guide through similar C principles to most high level languages. Here the syntax may be slightly different but the concepts exactly the same.

C does have a few surprises:

• Many High level languages, like PASCAL, are highly disciplined and structured.
• BEWARE - C is much more flexible and free-wheeling. This freedom gives C much more power that experienced users can employ.

• C Program Structure
• Variables
  • Defining Global Variables
  • Printing Out and Inputting Variables
• Arithmetic Operations
• Comparison Operators
• Logical Operators
• Order of Precedence
• Exercises
