what is a special type of variable used in subroutines that refers to a piece of data?\n a parameter\n a constant\n a function\n a routine
Answer
Brief Explanations:
In subroutines, a parameter is a special - type variable that refers to a piece of data. A constant has a fixed value and doesn't refer to data in the way parameters do. A function is a block of code for a specific task, not a variable for data reference. A routine is a general term for a sequence of instructions, not a variable for data reference.
Answer:
a parameter
