Chapter 4

1. Methods with no parameters are called niladic methods.
2. Methods with only one parameter are called monadic methods.
3. Methods with two parameters are called dyadic methods.
4. Methods with three parameters are called triadic methods.
5. Methods with more than three parameters are called polyadic methods.
6. You should avoid duplicate code. It is not a productive way to program, can make programs unnecessarily large, and has the propensity to proliferate the same exception throughout your codebase.
7. Functional programming is a software coding methodology that treats computations as the mathematical evaluation of computations that does not modify state.
8. The advantages of functional programming include safe code in multithreaded applications and smaller, more meaningful methods that are easy to read and understand.
9. Input and output can be a problem for functional programs as it relies on side-effects. Functional programming does not allow for side-effects...
