Arrays

At their simplest, arrays can turn a single variable into a list of multiple variables. Another way to look at it is that an array is a collection of common data elements chosen from any of the various data types available to variables. These elements are addressed by an index number that points to a specific data element. We used both numerical and character arrays in our project code to store our answers, pin assignments, and sensor readings. To put an array to use we begin with an array declaration.

Declaring Arrays

Declaring an array is very similar to declaring any other variable. The simplest form of array declaration can be seen in this following example:

int myArray[3];

This basic array creates three separate variables referred ...
