tippingtable2gui -格式化问题c#

我对格式有问题。然而，我似乎无法使它看起来合适。

我被告知在进入嵌套while循环之前初始化tipRate，或者只使用for循环。但是我仍然对格式有问题。

应该是什么样子

我的是什么样子

我的代码

好吧，您应该用伪代码写出来，然后将伪代码转换为实际代码。你想循环遍历所有可能的价格，对于每个价格循环遍历所有可能的小费百分比。在哪里"初始化"变量是很重要的。

initialize dinnerprice, maxDinner and maxTip
while dinnerprice <= maxDinner
begin
    set the tiprate to minimum  (This needs to be done at the start of every dinnerprice)
    while tiprate <= maxtiprate
    begin
        calculate tip
        print the tip in the appropriate place
        increment the tiprate
    end
    increment the dinnerprice
end
