Question 1: What is the output of the following C++ code?

int list[5] = {0, 5, 10, 15, 20};
int j;
for (j = 1; j <= 5; j++)
     cout << list[j];

       0 5 10 15 20
       5 10 15 20 0
       5 10 15 20 20
       Code contains index out of bounds

Question 10: In a class, all function members

Question 2: What is the value of alpha[4] after the following code executes?

int alpha[5] = {0};
int j;
alpha[0] = 2;
for (j = 1; j < 5; j++)
     alpha[j] = alpha[j - 1] + 3;        5
       8
       11
       14

Explanation / Answer

1.(d) Code contains index out of bounds

Expl:- List Size is 5 and list[0] to list[4] is valid, list[5] is invalid

2.(d) 14

3.(d) 10

Expl:- when j=3 then alpha[3]=3+8

but when j=2 then alpha[2+1]=2+5+3=10 (as 2%2=0) so the if condition gets satisfied

4.(b) cin >> alpha[0] >> alpha[1] >> alpha[2];

Expl. Array always starts with an zero index

5.(b) 50

Expl:- Number of rows*number of columns=Number of components

6.(a) list has 10 rows and eight columns.

7.(d) 0 1 2
2 3 4
4 5 6
6 7 8

8.(a) sum = 0;
for(j = 0; j < 10; j++)
sum = sum + sale[j][3];

Expl. sale[j][3] means all the rows of fourth column

9.(b) an object type.

10.(a) must be public and all member variables must be private

Expl:- member functions should be public so that the class object can access them

member variables should be private so that only member functions should access them and not class objects.
