Answer 1

Answer:

Hi.

The correct answer is b. 13.

Explanation:

The values when the iteration was finished is.

• alpha[0]= 5

• alpha[1]= 8

• alpha[2]= 10

• alpha[3]= 13

• alpha[4]= 15

Before iteration alpha[0] = 5.

First iteration alpha[1] = 5 + 3 = 8.

Second iteration alpha[2] = 8 + 2 = 10.

Third iteration alpha[3] = 10 + 3 = 13.

Last iteration alpha[4] = 13 + 2 = 15.
