练习7:更多的打印–笨方法学ruby在线

现在我们将做一批练习,在练习的过程中你需要输入程式代码,并且让它们运行起来,我不会解释太多,因为这节的内容都是以前熟悉的。这节练习的目的是巩固你学到的东西,我们几轮练习后再见。不要跳过这些练习,不要复制贴上!

puts "Mary had a little lamb."
puts "Its fleece was white as %s." % 'snow'
puts "And everywhere that Mary went."
puts "." * 10  # what'd that do?

end1 = "C"
end2 = "h"
end3 = "e"
end4 = "e"
end5 = "s"
end6 = "e"
end7 = "B"
end8 = "u"
end9 = "r"
end10 = "g"
end11 = "e"
end12 = "r"

# notice how we are using print instead of puts here. change it to puts
# and see what happens.
print end1 + end2 + end3 + end4 + end5 + end6
print end7 + end8 + end9 + end10 + end11 + end12

# this just is polite use of the terminal, try removing it
puts
