源码ex6-2.rb ：
types_of_people = 10 x = "There are #{types_of_people} types of people." binary = "binary" do_not = "don‘t" y = "Those who know ‘#{binary}‘ and those who #{do_not}." z = ‘Those who know "#{binary}" and those who #{do_not}.‘ puts x puts y puts "I said: #{x}" puts "I also said: ‘#{y}‘." puts "I also said: ‘#{z}‘."
结果是：
[ufindme@ufindme rubywork]$ ruby ex6-2.rb There are 10 types of people. Those who know ‘binary‘ and those who don‘t. I said: There are 10 types of people. I also said: ‘Those who know ‘binary‘ and those who don‘t.‘. I also said: ‘Those who know "#{binary}" and those who #{do_not}.‘.
这里注意一点：
双引号里面的单引号是原样输出，而单引号里面的双引号也是原样输出。
双引号里面的变量的输出时，变量用实际的值代替后输出显示。
单引号是不管引号里面的是什么，都源码输出，也没有替代。
