printf("\a"); is not working in c language

Question

here's my full code -

#include<stdio.h>
int main()
{
    int a = 100;
    float b = 5.55;
    printf("my a = %d and my b = %f",a,b);
    printf("\a");
    return 0;

}

it runs perfectly and didn't gave any error but it also it didn't gave any sound beep or alarm sound.
