在 C++ 中使用“\a”发出哔声在 Mac 上的 xcode 中不起作用

Question

I am making a program that makes a beep noise in Xcode on a MacBook pro. The speakers on my computer are on and the volume is on max yet I can't hear anything. This is my program, can you please tell me why it is not working?

int main(int argc, const char * argv[]) {
    std::cout << "\a";
    return 0;
}

Is there a way to make a beep noise using only "\a"?

Answer 1

Stop at any step if it works!

1. Go to Terminal > Preferences > Settings > Advanced and tick the Audible Bell option.

2. Also make sure that in System Preferences > Sound , the slider for Alert Volume is not on its leftmost setting.

3. Try restarting your system if you've updated it.

4. Try running the generated executable on terminal instead of XCode's integrated terminal.

5. Check if terminal beeps on this command: $ printf \\a .

Even after all these if you don't get any beep sound then go through the steps mentioned in this solution . Or ask it on Apple SE or Apple Discussion Forums.
