值的实际表示由机器体系结构决定(严格来说,由C实现)。实际大小可以通过itemsize属性访问。因为Python的普通整数类型不能表示整个范围的C的无符号(长整数)整数,所以存储for'L'和'I'items 的值将在检索时表示为Python长整型。 该模块定义了以下类型: class array.array(typecode[, initializer]) 一个新的数组
You can store multiple variables of the same type in an array data structure. You declare an array by specifying the type of its elements. If you want the array to store elements of any type, you can specify object as its type. In the unified type system of C#, all types, predefined...
{ 0, 1, 2, 3 }; // display contents " 0 1 2 3" for (const auto& it : c0) { std::cout << " " << it; } std::cout << std::endl; // display first element " 0" Myarray::pointer ptr = c0.data(); std::cout << " " << *ptr; std::cout << std::endl; ...

Copy var v:Vector.<String>; v = new Vector.<String>(); A variable declared with the Vector.<T> data type can only store a Vector instance that is constructed with the same base type T. For example, a Vector that's constructed by calling new Vector.<String>() can't be assigned to...

std::array是一个聚合类型,其语义等同于保有一个C语言风格数组T[N]作为其唯一非静态数据成员的结构体,但其不同于C数组的是它不会自动退化为T*。同时该结构体结合了C风格数组的性能、可访问性和容器的优点(可获取大小、支持赋值和随机访问等)。 2. array的用法 ...
