i have not clue what answer could be plzzz and explain

(c) 4

Explanation:

Let us represent number with Ni

the first number is 20

first stage program execution: is N0 (20) greater than 0

20 > 0

hence

N1 = 20/2 = 10

count = 1

second stage program execution: is N1 (10) greater than 0

10 > 0

hence

N2 = 10/2 = 5

count = 2

third stage program execution: is N2 (5) greater than 0

5 > 0

hence

N3 = 5/2 = 2.5

count = 3

first stage program execution: is N3 (2.5) greater than 0

2.5 > 0

hence

N3 = 2.5/2 = 1.25

count = 4

the program however terminates here as number is supposed to be an integer, not a float. Hence for N3 = 2.5 being a float, not an integer, there is a count but the program ends.
