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

Consider the following declaration of a two-dimensional array in C:

char a[100][100];

Assuming that the main memory is byte-addressable and that the array is stored starting from memory address 0, the address of a[40][50] is

The value of j at the end of the execution of the following C program

int incr (int i)
{
     static int count = 0;
     count = count + i;
     return (count);
}
main () {
   int i,j;
   for (i = 0; i <= 4; i++)
   j = incr(i);
}

is

Consider the following C function definition

int Trial (int a, int b, int c)
{
       if ((a > = b) && (c < b)) return b;
       else if (a > = b) return Trial (a,c,b);
       else return Trial (b,a,c);
}

The function Trial:
