Cyclomatic complexity is a software metric used to measure the number of linearly independent pathways in a code section. Developed by Thomas J. McCabe in 1976, it is a numerical assessment of the complexity of a program and is calculated using the program’s Control Flow Graph.
The Control Flow Graph’s nodes represent a group of instructions in the program, and its directed edges connect two nodes if the second command may be executed right after the first. The higher the number of independent pathways, the higher the complexity of the program.
Cyclomatic complexity is essential in software development as it helps developers identify areas in the code that may require additional testing or refactoring to reduce complexity, enhance readability, and improve performance. It helps developers to maintain code quality and identify potential bugs that may arise when the codebase expands.
