我在阅读时在一个源上看到了这个char szPrivateKey[]定义，所以我去检查它是什么，奇怪的是，当程序运行时它会发出声音。这里有复活节彩蛋吗？（使用visual studio 2003/windows编译）

字符0x07是 ASCII 响铃字符。支持各不相同，但将其发送到控制台通常会产生单一的哔声。

szPrivateKey因为- 0x07 或 CTRL-G中有一个 0x07（在以 0xBA 开头的行） ，在大多数系统上，它将是一个BEL字符，所以它会在旧电传打字机上响铃。现代计算机，甚至 30 年前的终端，都没有机械铃（打字机也没有，如果你现在能找到的话），所以他们用哔声代替。

在 C 和 C++ 中，您可以在字符串中创建一个 BEL 字符"\a"（并且它在不使用 ASCII 的系统上也可以正常工作，它会在非 ASCII 系统中生成任何相应的字符）。

顺便说一句，这不是“复活节彩蛋”，它是打印一些不是真正“文本”的东西的结果，所以不应该用cout. 你可以得到相同的type myfile.dat东西或类似的东西（假设myfile.dat是一个二进制文件，其中有一个 0x07 字节）。

这是 ascii 表的前 10 个条目：

请注意 ascii 代码 7 ，如果您向其写入该字符，许多终端会发出声音。

\a，也称为，在大多数机器中BEL都有一个 vlue 。0x07

从 C++11 2.14.3

警报 BEL \a

从 C99 5.2.2

\a(alert) 在不改变活动位置的情况下产生声音或可见的警报。
