问题描述

提前道歉，因为我敢肯定有人一定曾经问过这个，但我找不到。

Apologies in advance as I'm sure someone must have asked this before but I can't find it.

一个同事和我都感到惊讶将相同的值添加到一个枚举中，然后对其进行编译，例如

Just had a surprise, a colleague and I both added the same value in for an enum, and it compiled, e.g.

  enum MyEnum
  {
    mine = 1,
    his = 1
  }

看起来像C / C ++支持这也是（？）。出于任何原因，是否有用？我看到了一种人类语言不同的案例（一个= 1，eins = 1，等等），但我不相信

Looks like C/C++ supports this also (?). Any reason for this behaviour, any cases where it's useful? I saw one case with difference human languages (one = 1, eins = 1, etc) but I'm not convinced

谢谢

推荐答案

让我们举一个简单的例子

Let's take a simple example

enum PrivilegeLevel
{
    None,
    Reporter,
    Reviewer,
    Admin,
    DefaultForNewUser = None,
    DefaultForProjectOwner = Reviewer,
};
