● ​Assume all the required header files are already being included in
the code.
●​ ​The function random(n) generates an integer between 0 and n-1

void main()
{
randomize();
int N=random(3),M=random(4);
int DOCK[3][3] = {{1,2,3},{2,3,4},{3,4,5}};
for(int R=0; R<N; R++)
{
for(int C=0; C<M; C++)
cout<<DOCK[R][C]<<" ";
cout<<endl;
}
}
(i) (ii)
1 2 3 1 2 3
2 3 4 2 3 4
3 4 5

(iii) (iv)
1 2 1 2
2 3 2 3
3 4

Ans Correct Options : (ii) and (iii)

Maximum value of N = 2
Maximum value M = 3

(1 Mark for writing the correct options)
NOTE: No marks to be awarded for writing any other option or any other
combination

(½ Mark for writing correct Maximum value of N)
(½ Mark for writing correct Maximum value of M)

2. (a) Differentiate between protected and private members of a class in context of 2
Object Oriented Programming. Also give a suitable example illustrating
accessibility/non-accessibility of each using a class and an object in C++.

Ans
private protected
Implicit Visibility Mode Explicit Visibility Mode

Not accessible to member functions of Accessible to member functions of
derived class derived class
Example:
class A
{
int X;
