Solution 2:

If you're using Windows OS then there is a function called 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:

echo -e "\007" >/dev/tty10

And if you do not wish to use Beep() in windows you can do:

echo "^G"
