How to initialize an array of struct in C++?
提问by Alexander Galkin
I have the following structin my C++ code (I am using Visual Studio 2010):
我的structC++ 代码中有以下内容（我使用的是 Visual Studio 2010）：
struct mydata
{
string scientist;
double value;
};
What I would like to do is to be able to initialize them in a quick way, similar to array initialization in C99 or class initialization in C#, something á la:
我想要做的是能够以快速的方式初始化它们，类似于 C99 中的数组初始化或 C# 中的类初始化，一些á la：
mydata data[] = { { scientist = "Archimedes", value = 2.12 },
{ scientist = "Vitruvius", value = 4.49 } } ;
If this is not possible in C++ for an array of structs, can I do it for an array of objects? In other words, the underlying data type for an array isn't that important, it is important that I have an array, not a list, and that I can write initializers this way.
如果这在 C++ 中对于结构数组是不可能的，我可以为对象数组做到这一点吗？换句话说，数组的底层数据类型并不重要，重要的是我有一个数组，而不是一个列表，而且我可以用这种方式编写初始化程序。

The syntax in C++ is almost exactly the same (just leave out the named parameters):
C++ 中的语法几乎完全相同（只是省略了命名参数）：
mydata data[] = { { "Archimedes", 2.12 },
{ "Vitruvius", 4.49 } } ;
In C++03 this works whenever the array-type is an aggregate. In C++11 this works with any object that has an appropriate constructor.
在 C++03 中，只要 array-type 是agregate 就可以工作。在 C++11 中，这适用于任何具有适当构造函数的对象。
