1. (TCO 1) What is the output of the following C++ code? int list[5] = {0, 5, 10

Question

1. (TCO 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

2. (TCO 1) What is the value of alpha[3] after the following code executes?

int alpha[5] = {0};
int j;
alpha[0] = 5;
for (j = 1; j < 5; j++)
{
     if (j % 2 == 0) //see if j is an odd number
          alpha[j] = alpha[j - 1] + 2;
     else
          alpha[j] = alpha[j - 1] + 3;
}
      10
      13
      15
      17

Explanation / Answer

1) since list[5] does not exist

Code contains index out of bounds

2) 13

alpha[1] = alpha[0] + 3;
alpha[1] = 5 + 3;
alpha[2] = alpha[1] + 2;
alpha[2] = 8 + 2 = 10
alpha[3] = alpha[2] + 3;
alpha[3] = 10 + 3 = 13;

so alpha[3] contain 13.

3) alpha[3] = 3 + 5 = 8;

alpha[3] = alpha[2] + 3;
alpha[2] = 2+7 = 7;

alpha[3] = 7 + 3 =10;

so alpha[3] will be having value 10.

4)int alpha[] = {3, 5, 7, 9, 11};

5)   strange(alpha[0], alpha[1]); // only integers we can pass as values.

6)   OPTION C
0 1
1 2
2 3

7) Both (i) and (ii) are correct way of intializing the alpha

8) OPTION A

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

9) an object type.

10) and member variables can be either public or private.
