Program Doesnt intercept SIGQUIT specifically?

Question

this program seems to not being able to intercept SIGQUIT signal Althought it can intercept SIGINT

void sig(int sig){
    printf("Got signal(%d)", sig);
}
int main(){
    signal(SIGQUIT, sig);
    char x[10];     fgets(x, 10, stdin);
}

I am running ubuntu 20 and running stty -a command gives first line output which i guess mean SIGQUIT is correctly mapped to ^D but pressing it seems to do nothing .I also tryied with ^\ since i am confused between quit=^\ and eof=^D as stty says so if someone can clear this misunderstanding between both two.

intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
