f) Read the following C++ code carefully and find out, which out of the given
options (i) to (iv) are the expected correct outputs of it. Also, write the

maximum and minimum value that can be assigned to the variable score
used in the code. 2

#include<iostream.h>
#include<stdlib.h>
void main()
{ randomize();
int guess[4]={ 100, 50, 200, 20 };
int score=random(2) +2;
for( int c=0; c<score; c++)
cout<<guess[c]<<”#”;
}

Outputs:
(i) 100#
(ii) 50# 200#
(iii) 100#50#200#
(iv) 100#50
Ans: Minimum value =2 maximum=3
Correct output is (iii)
2. a) What is the difference between the members in private visibility mode and

the members in protected visibility mode inside a class? Also give a suitable
C++ code to illustrate the same. 2

Ans:
