CBSE AISSCE 2017-2018 Marking Scheme for Computer Science
(2018-2019 Sub Code: 083 Paper Code: 91)

NOTE:
● Marks not to be awarded for partially correct answer
● Ignore the mention of Constructors

(iii) Write the names of all the members, which are directly accessible by the object S
of class Schedule declared in the main() function.
Ans View(), Start()
Display(), Initiate()

(1 Mark for writing all correct member names )
NOTE:
● Marks not to be awarded for partially correct answer
● Ignore the mention of Constructors
(iv) What will be the order of execution of the constructors, when the object S of class
Schedule is declared inside main() function?

Ans Course(), Teacher(), Schedule()

(1 Mark for writing correct order)
NOTE:
● No Marks to be awarded for any other combination/order.
● Names of the constructor/class without parentheses is acceptable
3 (a) Write the definition of a function SumEO(int VALUES[], int N) in C++, which 2
should display the sum of even values and sum of odd values of the array
separately.
Example: if the array VALUES contains
25 20 22 21 53

Then the functions should display the output as:
Sum of even values = 42 (i.e 20+22)
Sum of odd values = 99 (i.e 25+21+53)

Ans void SumEO(int VALUES[], int N)
{
int SE = 0, SO = 0;
​ for (int I=0;I<N;I++)
{
if(VALUES[I] %2 == 0)
SE += VALUES[I];
else
SO += VALUES[I];
}
cout<< "Sum of even values = " << SE<<endl;
cout<< "Sum of odd values = " << SO<<endl;
}
OR
Any other correct alternative code in C++
(½ Mark for correctly writing the loop)
(½ Mark for adding even elements)
