How to produce beep sound using "\a" escape character?

Question

If I write the following program, then there is no beep sound on running the code.

#include <stdio.h>
int main()
{ 
    printf("\a");
    return 0;
 }

Can you tell me how to use \a for producing beep sound using C program ?

Answer 1

The only thing wrong (half wrong) with your program is main signature.

To be 100% portable it should be int main(void) or int main(int argc, char **argv) or equivalent: int main() is not equivalent.

And I'd print a '\n' too, or flush the output buffer rather than relying on the runtime flushing all buffers for me automatically, but your program should sound the bell as it is. If it doesn't the problem is elsewhere, not with C.

#include <stdio.h>
int main(void)
{
    printf("\a\n");
    return 0;
}

i usually use another way to get the beep sound it works 100% on windows 7.

    int x=7; //7 is beep sound other numbers may show emoji and characters
    printf("%c",x);
