Which statement about local variables is valid?

• A. the data type of a local variable is determined by its value
• B. Local variables must be declared with an explicit type
• C. Local variables cannot hold lists
• D. Local variables are only for debugging

Answer: (A)

In Appian, local variables pick up their type from the value you assign to them. If you set a local variable to a numeric value, its type becomes numeric; if you assign a list, it becomes a list type; a string becomes text, and so on. This means you don’t have to explicitly declare a type for every local variable—the value itself determines the type. You also have the option to declare an explicit type if you want to enforce a specific type, but it’s not required. That’s why the statement about the data type being determined by its value is the correct one. Local variables can indeed hold lists, they’re not only for debugging, and while you can specify a type explicitly, it isn’t mandatory.
