List the conditional structures offered by a programming language. See Wikipedia: conditionals for descriptions.

Common conditional structures include if-then-else and switch.

Less common are arithmetic if, ternary operator and Hash-based conditionals.

Arithmetic if allows tight control over computed gotos, which optimizers have a hard time to figure out.



i = random 10
if i mod 2 = 0
  print i & " is divisible by 2"
elif i mod 3 = 0
  print i & " is divisible by 3"
else
  print i & " is not divisible by 2 or 3"
