Explanation / Answer

(TCO 1) Assume you have the following declaration:

char nameList[100];

Which of the following ranges is valid for the index of the array nameList? (Points : 4)
0 through 99

2. (TCO 1) What is stored in alpha after the following code executes?

int alpha[5] = {0};
int j;
for (j = 0; j < 5; j++)
{
alpha[j] = j + 5;
if ( j % 2 == 1) //see if j is an even number
alpha[j - 1] = alpha[j] + 2;
}

alpha = {8, 6, 10, 8, 9}

3. (TCO 1) What is stored in alpha after the following code executes?

int alpha[5] = {0};
int j;
for (j = 0; j < 5; j++)
{
alpha[j] = j + 1;
if (j > 2)
alpha[j - 1] = alpha[j] + 2;
}

(Points : 4)
alpha = {1, 2, 6, 7, 5}

4. (TCO 1) Consider the following declaration:

int alpha[3];

Which of the following input statements correctly inputs values into all the array elements of alpha? (Points : 4)

cin >> alpha[0] >> alpha[1] >> alpha[2];

5. (TCO 1) Consider the following statement:

double alpha[10][5];

The number of components of alpha is ____. (Points : 4)

50

6. (TCO 1) After the following statements execute, what are the contents of matrix?

int matrix[4][3] = {0};
int j, k;
for (j = 0; j < 4; j++)
for (k = 0; k < 3; k++)
matrix[j][k] = 2 * j + k;

(Points : 4)

    0 1 2
    2 3 4
    4 5 6
    6 7 8

7. (TCO 1) Given the following two-dimensional array, which statement correctly sets the third column and fourth row element = 25.0?
