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;
         


        

Answer 1

Please list your operating system, how did you run your code, and if your computer has a beeper.

If you use Windows, maybe this Q&A How to make a Beep sound in C on Windows? would help you.

If you use a GUI desktop Linux distro, terminal emulator like gnome-terminal or xfce4-terminal have a preference option bell to check. Then, make sure your speaker works.

The code below works well for me:

/* name: bell.c
 * run: gcc bell.c && ./a.out
 */

#include 

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

By the way, your code is not the problem.
