Require 3 Path test cases.
Test Case 1 - A is any value > 9 and C = 100 to check that
nothing is printed.
Test Case 2 - A is any value < 10 and C is > 100 to check
that Print A and
Print C is greater than A lines are printed
Test Case 3 - A is any value, and C is < 100 to check that
Print A ( only if A is < 10)
Print C is greater than A is printed.
We should use Cyclomatic complexity formula to calculate
number of paths easily
C = E - N + 2
