If you're using Windows OS then there is a function called Beep()
如果您使用的是 Windows 操作系统，那么有一个函数叫做 Beep()
#include <iostream>
#include <windows.h> // WinApi header
using namespace std;
int main()
{
Beep(523,500); // 523 hertz (C5) for 500 milliseconds
cin.get(); // wait
return 0;
}

For Linux based OS there is:
对于基于 Linux 的操作系统，有：
echo -e "echo "^G"
7" >/dev/tty10
And if you do not wish to use Beep()in windows you can do:
如果您不想Beep()在 Windows 中使用，您可以执行以下操作：
char d=(char)(7);
printf("%c\n",d);

There are a few OS-specific routines for beeping.
有一些特定于操作系统的蜂鸣例程。
On a Unix-like OS, try the (n)curses beep() function. This is likely to be more portable than writing
'\a'as others have suggested, although for most terminal emulators that will probably work.In some *BSDs there is a PC speaker device. Reading the driver source, the
SPKRTONEioctl seems to correspond to the raw hardware interface, but there also seems to be a high-level language built aroundwrite()-ing strings to the driver, described in the manpage.It looks like Linux has a similar driver (see this articlefor example; there is also some example code on this pageif you scroll down a bit.).
In Windows there is a function called Beep().
在类 Unix 操作系统上，尝试(n)curses beep() 函数。这可能比
'\a'其他人建议的编写更便携，尽管对于大多数可能会工作的终端仿真器。在某些 *BSD 中有一个PC 扬声器设备。读取驱动程序源代码，
SPKRTONEioctl 似乎对应于原始硬件接口，但似乎也有一种高级语言围绕write()驱动程序的 -ing 字符串构建，如联机帮助页中所述。在 Windows 中有一个名为Beep()的函数。

alternatively in c or c++ after including stdio.h
在包含 stdio.h 之后，或者在 c 或 c++ 中
std::cout << '';
(char)7 is called the bell character.
(char)7 被称为铃字符。

cout << '\a';

Here's one way:
这是一种方法：
#ifdef WINDOWS
#include <Windows.h>
void beep() {
Beep(440, 1000);
}
#elif LINUX
#include <stdio.h>
void beep() {
system("echo -e "cout << "\a";
7" >/dev/tty10");
}
#else
#include <stdio.h>
void beep() {
cout << "\a" << flush;
}
#endif
From C++ Character Constants:
从C++ 字符常量：
Alert: \a
警报：\a

Easiest way is probbaly just to print a ^G ascii bell
最简单的方法可能只是打印一个 ^G ascii bell

You could use conditional compilation:
您可以使用条件编译：
##代码##回答by dams
In Xcode, After compiling, you have to run the executable by hand to hear the beep.
在 Xcode 中，编译后，您必须手动运行可执行文件才能听到哔哔声。
