问题描述

如何打印出僵尸的名字和墓地

How to print out the zombie's name and graveyard

您可以在不添加字符串的情况下将其串联吗?

Can you concatenate this without adding a string?

z = zombie.find(3)

puts z.name
puts z.graveyard

这是错误的吗?它只输出最后一个，墓地.

Is this wrong? It is only outputing the last one, graveyard.

推荐答案

您应该使用

puts "#{z.name} #{z.graveyard}"

您可能想知道如何评估它！您应该查看插值.表达式z.name和z.graveyard的结果被串联/插入到字符串中. #{ }中的所有表达式都会被求值并插入到字符串中

You might be wondering how this would get evaluated! You should look at Interpolation. The result of the expressions z.name and z.graveyard gets concatenated/inserted into the string. Any expression that goes into #{ } gets evaluated and inserted into the string
