how can we measure the software using cyclomatic complexcity?

Cyclomatic complexity measures the amount of decision logic in a single software module.

It is used for two related purposes in the structured testing methodology.
1. it gives the number of recommended tests for software.
2. it is used during all phases of the software lifecycle, beginning with design, to keep software reliable, testable, and manageable.
Cyclomatic complexity is based entirely on the structure of software’s control flow graph.

It is a measure of complexity of a program (algorithm).
it can be used only for small piece of code like small functions.
It gives minimum test cases required to execute each line of code.
It is best suited for unit testing written by developers.
The complexity is increaded by logic (with the use of loop and if-else state ments).
A progrma without any loop and if-else with all sequential statement have complexity 1.
It is a core White box technique.
Achieving the code coverage using complexity for a application code is nearly impossible as it will reruire years.
