1. Review the code and answer the following questions:

Note: ArcTool throws a syntax error when there is not a return after .end. File must end in a blank line.

a. Highlight the correct functionality of the subroutine Y

i. add integers a + b and store in c, break while loop when k = 0

ii. add arrays a + b and store in array c, break while loop when k > 0

iii. add arrays a + b and store in array c, break while loop when k < 0

iv. add integers a + b and store in c, break while loop when k < 0

v. add arrays a + b and store in array c, break while loop when k = 0

vi. add integers a + b and store in c, break while loop when k > 0

b. What is the final value for c:
