C ++中各个元素的静态数组初始化 [英] Static array initialization of individual elements in C++

问题描述

以下代码适用于GCC的C编译器，但不适用于C ++编译器。是否有一个捷径在C ++中实现相同的结果？

The following code works with GCC's C compiler, but not with the C++ compiler. Is there a "shortcut" to achieve the same result in C++?

int array[10] = {
    [1] = 1,
    [2] = 2,
    [9] = 9
};

Humm，我发现这一点，澄清一切。

推荐答案

这种初始化形式只在C99标准中定义。它不会适用于C ++。所以，你必须一个一个地分配你的元素：

This form of initialization is only defined in the C99 standard. It does not apply to C++. So, you'll have to assign your elements one-by-one:

int array[10] = { 0 };
array[1] = 1;
array[2] = 2;
array[9] = 9;
