When and how do you use a \a escape sequence?

Question

I came across this article on escape sequences. Have you used \a before?

https://docs.microsoft.com/en-us/cpp/c-language/escape-sequences?view=msvc-170

Answer 1

\a escape sequence is use for making a beep sound

it tells the compiler to produce a beep sound.

so whenever a compiler encounters a \a sequence, it produces a beep sound from the speakers of your system.

for example,

#include <stdio.h>

int main() {

printf("1\a2\a3\a4\a5\a6\a7\a8\a9\a0");
return 0;
}

This code will print 1 and make beep sound then 2 (beep sound)

then 3 beep sound

then 4 beep sound
and so on.

But in SoloLearn it does not works!
maybe it is not supported here.
