我使用这段代码让用户输入名称，而程序将它们存储在一个数组中，直到他们输入一个空字符串(他们必须在每个名称后按enter):
people = []
info = 'a' # must fill variable with something, otherwise loop won't execute
while not info.empty?
info = gets.chomp
people += [Person.new(info)] if not info.empty?
end
这段代码在do…while循环:
people = []
do
info = gets.chomp
people += [Person.new(info)] if not info.empty?
while not info.empty?
在这段代码中，我不需要将信息分配给一些随机字符串。
不幸的是，Ruby中似乎不存在这种类型的循环。谁能提出一个更好的方法来做这件事?
当前回答
这个怎么样?
people = []
until (info = gets.chomp).empty?
people += [Person.new(info)]
end
其他回答
这个怎么样?
people = []
until (info = gets.chomp).empty?
people += [Person.new(info)]
end
a = 1
while true
puts a
a += 1
break if a > 10
end
是这样的:
people = []
begin
info = gets.chomp
people += [Person.new(info)] if not info.empty?
end while not info.empty?
参考:Ruby的Hidden do {} while()循环
ppl = []
while (input=gets.chomp)
if !input.empty?
ppl << input
else
p ppl; puts "Goodbye"; break
end
end
这是另一个:
people = []
1.times do
info = gets.chomp
unless info.empty?
people += [Person.new(info)]
redo
end
end
