Subarray

What is subarray?
A subarray is usually defined as part or section of an array. An array is a set of variables that a programmer defines together. Instead of creating separate variables, the programmer can declare a single array with multiple values.
Programmers can do many of the same options on a subarray that they can do on the entire array. Allowing operations on a subarray makes these tools more versatile for storing multiple variables in a single specific set.

In various programming languages, uses of a subarray, such as sending the record to or from a method or function, generally contain much of the same syntax that is used with the entire array, with some subtle differences. Usually the name of the array is first used as a reference, and the exact subarray or part of the array is written in parentheses or brackets.
When using a subarray, programmers need to pay the same amount of attention to consistency as they would using an entire array or a single variable.

This implies that the values passed from one method or function to another are not changed by a bug or bug in the code, and that they can be accessed by any part of the code that requires those values. It can be useful to go through a written program in debug mode to see how the values are evaluated line by line when there is a problem with using a subarray.
