Which of the following statements is FALSE?

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.

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

Assume the following C variable declaration

int * A[10], B[10][10];

Of the following expressions

I. A[2]
II. A[2] [3]
III. B[1]
IV. B[2] [3]

Which will not give compile-time errors if used as left hand sides of assignment statements in a C program?

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 approximates
