完全嵌套循环和不完全嵌套循环有什么区别? [英] What is the difference between perfectly nested loop and imperfectly nested loop?

问题描述

我想知道完美嵌套循环和不完美嵌套循环有什么区别?

I wanted to know what is the difference between perfectly nested loop and imperfectly nested loop?

推荐答案

请参见:完全嵌套循环是其中所有内容都在最内层循环中的循环.例如，

A perfectly nested loop is one wherein all content is in the innermost loop. For instance,

foreach(var a in vals1)
{
    foreach (var b in vals2)
    {
        Console.WriteLine(a + b);
    }
}

与嵌套不完善的嵌套相比，

As compared to an imperfectly nested one,

foreach(var a in vals1)
{
    Console.WriteLine("values for " + a);

    foreach (var b in vals2)
    {
        Console.WriteLine(a + b);
    }
}

当然，我是C#专家，这是C#，我不认识的人都使用这样的术语，这一点都没有关系，但是您明白了这一点. 只要考虑一下在适当情况下编译的伪代码即可.

Of course, I'm a C# guy and this is C# where nobody I know of uses such terms and it doesn't matter at all, but you see the point. Just consider this pseudo-code that compiles under the right circumstances.
