**What is the cyclomatic complexity of a program?**

Cyclomatic complexity of a program tells us the quantitative measure of the complexity of a program.

**How to calculate Cyclomatic complexity?**

There are three methods;

**Count the number of regions on the graph:**4**No of edges – no. of nodes + 2:**11-9+2=4**No. of predicates + 1 :**3+1=4

**What are independent paths?**

Independent path is a path that has at least one edge that has not been traversed before in the given graph.

Here;

Independent paths are;

1, 9

1, 2, 3, 8, 1, 9

1, 2, 4, 5, 7, 8, 1, 9

1, 2, 4, 6, 7, 8, 1, 9

**What is the use of finding graph complexity and finding paths?**

It is used in software testing.
