嵌套直到循環(huán) (Nested until loop)
Alike for, while, and do...while, until loop can also be nested for meeting the specific purpose. In this type of nesting, two until loops work in the combination such that at first, the outer loop is triggered which results in the execution of the inner loop. The outer Until loop is not invoked as long as the inner loop does not comes out to be true. It is a kind of Entry control loop which simply means that first the outer Boolean expression is processed; if it is false then the pointer will move to the inner loop to check inner condition. The whole execution will take place in the same manner.
與for, while和do ... while一樣 , 直到循環(huán)也可以嵌套以滿足特定目的。 在這種嵌套中,兩個(gè)直到循環(huán)在組合中起作用,這樣一來(lái),首先觸發(fā)外循環(huán),從而執(zhí)行內(nèi)循環(huán)。 只要內(nèi)部循環(huán)不成立,就不會(huì)調(diào)用外部的直到循環(huán)。 這是一種Entry控制循環(huán),僅表示首先處理外部布爾表達(dá)式;然后進(jìn)行處理。 如果為假,則指針將移至內(nèi)部循環(huán)以檢查內(nèi)部條件。 整個(gè)執(zhí)行將以相同的方式進(jìn)行。

句法:

范例1:
=begin Ruby program to find the sum of numbers lying between two limits using nested until loop =endputs "Enter the Upper limit" ul=gets.chomp.to_i puts "Enter the Lower limit" ll=gets.chomp.to_iuntil ul==llnum=ultemp=ulsum = 0until num==0#implementation of until looprem=num%10num=num/10sum=sum+remendputs "The sum of #{temp} is #{sum}"ul=ul-1 endOutput
