For example, a variable could be speed. |

Declaration |
The process of assigning a type to a variable. For example, speed =8 sets the declaration to a integer number. |
Global variables |
Variables that are accessible from any part of a program. |
Local variables |
Variables that are only accessible in the scope in which they are declared. |
Scope of variables |
The area of a program within which a variable is accessible. |
Input |
Data that is sent to a computer for processing. |
Output |
