字符串数据长度的变化或数值型数据精度和等级的变化也表明在数据的表示、验证和使用上存在潜在的问题。

Variations in length for string data or in precision and scale for numeric data also point to potential issues in data presentation, validation, and usage.

字符串长度可能因语言的不同而变化。

String lengths can vary from language to language.

关于这点，那个数组的长度被存储在ArgC中，好的，让我们看看这个轻微的变化，那个揭示了我们可以做的，和字符串实际上是什么。

And in this context, the length of that array is stored in Arg C. Well, let's take a look at a slight variance of this that reveals further what we can do and reveals what a string really is.

b OK. In this example I'd use b. All right, as b get-- b is the thing that's changing as I go along here, but it could be things like, how many elements are there in a list if the input is a list, could be how many digits are there in a string if the input's a string, it could be the size of the integer as we go along. All right.?

好，在这个例子里我会用，因为b是一直在变的东西,但是也可能是如下情况：,如果输入是数组的话,变化的就是数组的元素数，如果输入是字符串的话,变化的就是字符串的长度，如果是integer的话,可能就是这个数的大小，对不对？
