4.2.1 Cyclomatic Complexity The measurement of cyclomatic complexity depends on the program's Control Flow Graph (CFG). A CFG uses graphical notations to model the control flow of a program. Nodes in a CFG repr

So, the cyclomatic complexity for this code is 3. Hope you now have a clear understanding of how to calculate cyclomatic complexity using the control flow graph (CFG). Next, you will learn where cyclomatic complexity can be applied and its significance in software development. Where Is Cyclomat...
Cyclomatic complexity serves as a vital gauge in computer science, quantifying a program's complexity by counting its independent paths. Monitoring this metric enables the pinpointing of problematic code sections prone to errors, facilitating easier main
Cyclomatic complexity is an important software quality metric. Learn how to calculate cyclomatic complexity. And get two cyclomatic complexity McCabe examples.

Consider the below Control flow graph: I have placed theREDdots to identify the Nodes andBLUElines to identify the edges: So here in this example: Number of Nodes (Red dots) = 14 Number of Edges (Blue Lines) = 15 So the Cyclomatic Complexity = N~E+2 = (14-15) +2 = 3 ...
P refers to the number of disconnected parts of the flow graph, such as a calling program and a subroutine. The equation represents the number of decisions plus one. In addition, binary decisions — such as “if” and “while” statements — add one to complexity. While Boolean operators ...

The complexityMis then defined as M = E - N + 2P 1. where E= the number of edges of the graph. N= the number of nodes of the graph. P= the number of connected components. For a single program,Pis always equal to1. So a simpler formula for a single subroutine is ...
