Compare Black box and White Box Testing. Find cyclomatic complexity of following code

$IF A= 10 THEN \\ IF B \gt C THEN - \\ \hspace{2 cm}A=B \\ \hspace{2 cm}ELSE A= C \\ END IF \\ END IF \\ \hspace{2 cm}PRINT A \\ \hspace{2 cm}PRINT B \\ \hspace{2 cm}PRINT C$

Comparison of Black box and White Box testing

1. Cyclomatic Complexity

1) Let us first number the given code

1. IF A=10 THEN
2. IF A>B THEN
3. A=B
4. ELSE A=C
5. END IF
6. END ID
7. PRINT A
8. PRINT B
9. PRINT C

2) Flow graph to compute cyclomatic complexity

Cyclomatic Complexity $= E – N + 2 \\ =9 – 9 + 2 \\ = 2$

Hence the Cyclomatic Complexity of given code is 2.
