fflush();
scanf("%c",&another);
}

if you enter any key it act as char and store in
"another",so before scanning we have to flush all the keys
hence fflush is used.

Answer / sight
You just remove the & in the last scanf statement
But also this loop will continue going on(infinite) b'coz
here no ending point.....
BTW if u remove those & it will definatly wait for entering
a charecter....
