Chris Pine, Learn to Program Chapter 3- Variables/Assignment

myString = '. . . you can say that again. . .'
puts myString
puts myString

# aissgn strings to variables (so, give strings a name so it's stored in the computer)
name = 'Patricia Rosanna Jessica Mildred Oppenheimer'
puts 'My name is ' + name + '.'
puts 'Wow! ' + name + ' is a really long name!'

# reassign different object to a variable
composer = 'Mozart'
puts composer + ' was "da bomb", in his day.'

composer = 'Beethoven'
puts 'But I prefer ' + composer + ', personally.'

# variables can point to any object, not just strings
var = 'just another ' + 'string'
puts var

var = 5 * (1+2)
puts var

# variables can point to anything but another variables
var1 = 8
var2 = var1
puts var1
puts var2

puts ''

var1 = 'eight'
puts var1
puts var2

# tried to point var2 to var1, it really pointed to 8 instead (just like var1 was pointing to). Then we had var1 point to  'eight', but since var2 was never really pointing at var1, it stays pointing at 8.
