Book: Data Structures and Algorithm Analysis in C++
Chapter: 1
Exercise: 1.3

Write a function to output an arbitrary double number (which might be negative) using only printDigit for I/O.

My problem(s) with this question:
1. What exactly is an arbitrary number?
2. How would it be negative unless I force it to be negative?
3. Is printDigit a function I need to use or do I make it myself?
4. Is there supposed to be an input for this to work properly?

I do have an idea on this problem, but it uses the rand() function. Am I correct?
