Answer»

The correct CHOICE is (c) class student{}S1,S2; s1=s2;

The best explanation: Only if the objects are of same class then their data can be copied from to another using assignment OPERATOR. This actually comes under operator OVERLOADING. Class constructors can’t be assigned any explicit value as in option class student{}s1; class topper{}t1; s1=t1; and class student{}s1; class topper{}t1; s1.student()=s2.topper();.
