Variables

Variables in Ruby

Ruby variables are assigned with =. You don't declare types — Ruby figures them out:

name = "Alice"    # String
age = 30          # Integer
height = 5.8      # Float
active = true     # Boolean

Ruby has four main scalar types:

• String — text in double or single quotes: "hello" or 'hello'
• Integer — whole numbers: 42, -7, 1_000_000
• Float — decimal numbers: 3.14, -0.5
• Boolean — true or false

There is also nil, Ruby's "nothing" value.

puts converts any value to a string before printing:

puts 42      # "42"
puts true    # "true"
puts nil     # (empty line)

Your Task

Create four variables:

• name = "Alice"
• age = 30
• height = 5.8
• active = true

Print each on its own line.
