dinmaic变量名 [英] dinmaic variable name
问题描述
嗨
让'我说我有20个变量名为a1-a20，它们都是相同的
类型（int）
我需要访问它们中的每一个并根据值执行一些
操作。
有什么方法可以在循环中访问它们并构建名称
dinamically或者我必须分别访问它们中的每一个吗？
Hi
let''s say I have 20 variables named a1-a20 which are all of the same
type (int)
I need to access each one of them and according to the value do some
operation.
Is there some way I can access them inside a loop and build there name
dinamically or do I have to access each one of them seperatly?

不，但听起来你应该存储val排在队列中。

No, but it sounds like you should store the values in an array.

不，但听起来你应该将值存储在数组中。

谢谢
数组将是个好主意但是我从
数据库表中获取这些值进入一个包含很多其他字段的结构
有没有办法转换这个结构？或者其他一些方式？
Thanks
An array will be a good idea however I am getting these values from a
DB table into a struct with a lot of other fields
Is there a way to transform this struct? Or maybe some other way?

不，但它听起来就像你应该将值存储在一个数组中一样。

阵列将是一个好主意但是我从
$ b获得这些值$ b DB表到一个包含很多其他字段的结构中
有没有办法转换这个结构？或者其他一些方式？

这取决于数据库的C包装器返回的内容。那些我用b / b
为每个数据库行返回一个数组，所以你应该能够
映射到另一个数组。
你的代码填充结构吗？

Ian Collins。
That depends on what the C wrapper to your database returns. Those I
have used return an array for each database row, so you should be able
to map to another array.
Is your code populating the struct?
