What is a variable in programming?

A statement that provides a data type and an identifier for a named constant
A named memory location whose contents can vary over time (correct)
A classification that describes the values that can be held by a data item
A program component’s name

Why do you need to include a declaration for a variable in most programming languages?

To provide a useful name for a value that won't change during a program's execution
To classify the values that can be held by the variable
To allocate memory for the variable and specify its data type and identifier (correct)
To specify the operations that can be performed on the variable

What distinguishes a named constant from a variable?

A named constant can only hold integer values, while a variable can store any data type
A named constant stores values in computer memory, while a variable does not
A named constant is called using its name, while a variable is invoked with function calls
A named constant can be assigned a value only once, while a variable can vary (correct)
