前些时候做过的一份面试试题[12]

public class cat : animals{

         public override void bit(){

                   console.write("bit by a cat!");

         }

}

public class test{

         public static void main(){

                   animals[] aa = new animals[2];

                   aa[0] = new dog();

                   aa[1] =  new cat();

                   foreach(animals a in aa) a.bit();

         }
