Question

所以问题是我试图让这个程序用来输入单词中给出的数字。我经常得到一个非法的表达错误开始。我是初学者，任何帮助将不胜感激。谢谢！

这是我的节目摘录

if(n>=1000)
    {
        System.out.println("OUT OF RANGE");
    }
    else
    {
        String result="", h=" ", t=" ", o=" ";
        int a=0,b=0,c=0;
        String ones[]= {"one","two","three","four","five","six","seven","eight","nine"};
        String teens[]={"eleven","twelve","thirteen","fourteen","fifteen","sixteen","seventeen","eighteen","nineteen"};
        String tens[]={"ten","twenty","thirty","forty","fifty","sixty","seventy","eighty","ninety"};
        if(n>=100 && n<1000)
        {
            a=n/100;
            result = [a-1]+"hundred"; //the problem occurs here.
            n=n%100;
        }

Answer 1

嗯。我发现了错误。抱歉浪费你的时间。

将是

 <h1>Edit existing pictures </h1>

 <% @pictures.each do |picture| %>
    <%= image_tag picture.attachment_url(:thumb) %>
    <%= link_to "Delete", picture_path(picture), method: :delete if user_signed_in? %>
 <% end %>

来自

 result = ones[a-1]+"hundred";

非常感谢。
