Software Engineering · Question 27 · Hard
What is the cyclomatic complexity of this procedure?
procedure adjust(a, n)
count = 0
for i = 1 to n
if a[i] > 0
count = count + 1
else if a[i] < 0
count = count - 1
while count > 10
count = count - 2
return count- 4
- 6
- 3
- 5
Answer and explanation
Answer: D. 5
Explanation: The procedure has 4 simple decision points: the for loop, the if, the else if and the while loop. Cyclomatic complexity = number of decisions + 1 = 5.
