Consider the following class definitions in a hypothetical Object Oriented
language that supports inheritance and uses dynamic binding. The language
should not be assumed to be either Java or C++, though the syntax is similar.
Px = new Q();
Qy = new Q();
Pz = new Q();
x.f(1); ((P)y).f(1); z.f(1);
Here ((P)y) denotes a typecast of y to P. The output produced by executing the above program fragment will be
Class P {
void f(int i) {
print(i);
}
}
Class Q subclass of P {
void f(int i) {
print(2*i);
}
}
Now consider the following program fragment:
Px = new Q();
Qy = new Q();
Pz = new Q();
x.f(1); ((P)y).f(1); z.f(1);
Here ((P)y) denotes a typecast of y to P. The output produced by executing the above program fragment will be

Consider the following C function.
float f,(float x, int y) {
float p, s; int i;
for (s=1,p=1,i=1; i < y; i++) {
p *= x/i;
s+=p;
}
return s;
}
For large values of y, the return value of the function f best approximates4
