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

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 
int main(void)
{
    printf("\a\n");
    return 0;
}
