# What is the formula for cyclomatic complexity?

## What is the formula for cyclomatic complexity?

3) Cyclomatic complexity V(G) = P +1 V (G) = 2 + 1 = 3 Where P is predicate nodes (node 1 and node 2) are predicate nodes because from these nodes only the decision of which path is to be followed is taken. Thus Cyclomatic complexity is 3 for given code.

### What is cyclomatic complexity in testing?

Cyclomatic complexity is a software metric used to indicate the complexity of a program. It is a quantitative measure of the number of linearly independent paths through a program’s source code. It was developed by Thomas J. McCabe, Sr. in 1976.

**What is cyclomatic complexity and how it is calculated?**

Cyclomatic complexity is a source code complexity measurement that is being correlated to a number of coding errors. It is calculated by developing a Control Flow Graph of the code that measures the number of linearly-independent paths through a program module.

**How is code complexity calculated?**

To calculate the cyclomatic complexity of our code, we use these two numbers in this formula: M = E − N + 2 . M is the calculated complexity of our code. (Not sure why it’s an M and not a C .) E is the number of edges and N is the number of nodes.

## How to calculate the cyclomatic complexity of a program?

Lower the Program’s cyclomatic complexity, lower the risk to modify and easier to understand. It can be represented using the below formula: Cyclomatic complexity = E – N + 2*P where, E = number of edges in the flow graph. N = number of nodes in the flow graph. P = number of nodes that have exit points

### How is the cyclomatic complexity of Virtusa calculated?

It is calculated by developing a Control Flow Graph of the code that measures the number of linearly-independent paths through a program module. Lower the Program’s cyclomatic complexity, lower the risk to modify and easier to understand. It can be represented using the below formula:

**How is McCabe’s cyclomatic complexity graph created?**

This metric was developed by Thomas J. McCabe in 1976 and it is based on a control flow representation of the program. Control flow depicts a program as a graph which consists of Nodes and Edges. In the graph, Nodes represent processing tasks while edges represent control flow between the nodes.

**How is cyclomatic complexity used in white box testing?**

Cyclomatic Complexity is software metric useful for structured or White Box Testing. It is mainly used to evaluate complexity of a program. If the decision points are more, then complexity of the program is more.
