Question

Occasionally, you will want to declare a variable that can be accessed by more than one function or script block in your program. You will need to declare that variable outside of any function definition, usually at the start of your script.

What term is used to describe this type of variable?

Answer 1

A variable that can be accessed by multiple functions or script blocks is called a global variable. These are declared outside of any function to make them accessible throughout the entire program.

Step-by-step explanation:

The term used to describe a variable that can be accessed by more than one function or script block in your program is known as a global variable. Global variables are declared outside of any function definition, usually at the start of your script, to make them accessible throughout the entire program. This contrasts with local variables that are declared within a function and can only be accessed by that specific function.

While global variables can be very useful for sharing data between different parts of a program, they can also make it difficult to track changes to that data, which can lead to bugs. That's why many programmers prefer to limit the use of global variables or use other patterns such as the module pattern or object-oriented programming to encapsulate and control access to data.
