'\A' not working in C in VS code

Question

0.00/5 (No votes)

See more:

In my laptop, I've tried to use the beep escape sequence (i.e. '\a'), it worked fie in codeblocks, but it isn't working at all in vs code even with the same code as what I wrote in codeblocks. I've seen c tutorials in c, so I do know that vs code do support this escape sequence, but idk why it isn't working in my case.

What I have tried:

A sample of code which I tried on both codeblocks and vs code is:

<pre>#include<stdio.h>

int main()
{
    printf("\a");
    _sleep(1000);
    printf("\a");
    return 0;
}

(btw, here I wrote \a 2 times, but it wasn't working even when I wrote it only once).

Try adding a second backslash character, an escape character,

"\\a"

Works fine for me, though if you're expecting a beep out of the internal PC speaker, that's not where the sound comes from. Today, a "beep" would be whatever sound is configured in the Windows Sound control panel and come out of the sound card/motherboard audio and any speakers attached to that.

To see if you have a beep sound configured, open Control Panel -> Sound -> Sounds tab -> Default Beep. If there is a speaker next to "Default Beep", there is a sound configured. Click "Default Beep" and the "Test" button to hear that sound. That's the sound you'll get from your code when the "\a" character is used.

Solution 2

printf() may not flush the output buffer until a newline ('\n') is seen, or the output buffer is full. Try adding fflush(stdout); after each printf(), to force the buffer to be flushed.
