爲什麼我聽到這個程序發出嘟嘟聲？

我在閱讀時看到了一個關於源代碼的定義，所以我去檢查一下它是什麼，奇怪的是，當程序運行時會發出聲音。這裏或其他地方是否有復活節彩蛋？（使用visual studio 2003/windows編譯）爲什麼我聽到這個程序發出嘟嘟聲？

一些人物尖叫（哦，可怕！） – valdo

它看起來像你的程序試圖表達它對你的愛。 –

如果你用足夠隨機的字節進行嘗試，你肯定會看到拿撒勒人耶穌的臉。 –

因爲有在szPrivateKey一個0×07（在該行開始0xBA） - 0×07，或CTRL-G，在大多數系統中，將是一個BEL字符，所以環的老電傳鍾。現代電腦，甚至30年曆史的終端都沒有機械的鐘聲（如果你最近可以找到的話，也不用打字機），所以他們用嘟嘟聲代替。

在C和C++中，你可以用"\a"作爲字符串中的BEL字符（在沒有使用ASCII的系統上它也可以正常工作，它將在非ASCII系統中生成任何相應的字符）。

順便說一下，這不是一個「復活節彩蛋」，它是打印非真正「文本」的東西的後果，所以不應該與cout一起顯示。你可以使用type myfile.dat或類似的東西（假設myfile.dat是一個二進制文件，並且有一個0x07字節）。

在舊的ASR33打印隨機二進制TTY總是相當不錯的一個表演 - 類型輪會自旋劇烈旋轉，鈴會響起，平臺會繼續前進。（雖然令人驚訝的是很少的回車以隨機二進制返回 - 它往往會跑到右邊並坐在那裏，從而在頁面的右側產生污跡。） –

當有人意外打印時，它總是「有趣」在我們在學校和早期工作場所使用的大型打印機上的二進制文件 - 是的，它似乎是更多的換行符和換頁符，因爲某些原因，回車符是/ –

字符0x07是ASCII鈴聲字符。支持各不相同，但將其發送到控制檯通常會導致一聲嘟嘟聲。

\a，也被稱爲BEL，在大多數機器中都有0x07的線索。

從C++ 11 2.14.3

警報BEL \一個

從C99 5.2.2

\一個（警報）產生可聽或可見的警報而不改變活動的位置。

'0x0B'是垂直製表符。 – user2357112

哦，有趣的，該死的，現在使用C++已經有近3年了，而且還有驚喜！將盡快接受S.O允許 –

@Viniyo Shouta：這與C++無關。這是關於特定輸出設備的特定屬性。 – AnT

爲什麼我聽到這個程序發出嘟嘟聲？
