What type of variable can be marked as constant in Avaloq Script?

• A. Variables that can be reassigned
• B. Variables that represent mutable data
• C. Variables meant for fixed reference
• D. Variables that are never declared

Answer: (C)

In Avaloq Script, variables that can be marked as constant are those meant for fixed reference. This means that once these variables are assigned a value, that value cannot change throughout the program's execution. Defining a variable as constant improves code reliability and readability, as it signals to the developer and anyone maintaining the code that certain data should not be altered. For instance, constants may be used for configuration settings, mathematical constants, or any other values that remain the same across the system’s operation. This guarantees that any part of the code that relies on these constants will always use the same intended value, thereby reducing errors that could arise from unintentional modifications. Other types of variables, like those that can be reassigned or represent mutable data, inherently allow their values to change, which is contrary to the purpose of a constant. Variables that are never declared don't fit into any category for being constant, as they lack a defined type or value. Thus, constants are specifically designated for fixed reference and provide a clear mechanism for ensuring certain information stays stable.
