Introduction To Ruby
If As A Modifier
Ruby is full of cute and interesting ways to make code more natural to write. The following program shows an alternative way to write an if statement.
# If as a modifier
x = 5
puts "x is 5" if x==5
You cannot write an else clause with this method.
- The following table shows a list of ages and one of the legal rights that a person gets when they reach that age. Use this information to write a program where the user can enter their age and see a list of the legal rights they have. Write this program using a series of statements like the above example.
- 12: See a 12A-rated film at the cinema without an adult.
- 14: Have a job which can be described as 'light work'.
- 15: See a 15-rated film at the cinema without an adult.
- 16: Enter a pub on your own. You cannot buy alcoholic drinks.
- 17: Donate blood.
- 18: Serve on a jury.
- 21: Adopt a child
- Look through any other programs you have written with if statements. Try to refactor them so that they use the modifier approach.
