[<< wikibooks] Programming Fundamentals/Typedef - An Alias
An explanation of typedef being used to create an alias data type.


== General Discussion ==
The typedef statement allows the programmer to create an alias, or synonym, for an existing data type. This can be useful in documenting a program. The C++ programming language syntax is:

Let's say a programmer is using a double data type to store the amount of money that is being used for various purposes in a program. He might define the variables as follows:


=== Example 1: Regular Definition of Variables ===

However, he might use the typedef statement and define the variables as follows:


=== Example 2: Using typedef when Defining Variables ===

The typedef statement is not used very often by beginning programmers. It usually creates more confusion than needed, thus stick to using the normal data types at first.
