What should be the cyclomatic complexity

We use cyclomatic complexity to get a sense of how hard any given code may be to test, m aintain, or troubleshoot as well as an indication of how likely the code will be to produce errors.A cyclomatic complexity value between 5 and 7 is when things start unravelling.Algorithm 1 find mccabe's cyclomatic complexity input:Filename too long in git for windows.I am trying to understand how cyclomatic complexity work, could someone explain to me why the following code gives a score of 3:

What is the difference between cyclomatic complexity and essential cyclomatic complexity?And now the algorithm for mccabe cyclomatic complexity a.When your code is in that range, its complexity becomes noticeable.So, if the configured maximum cyclomatic complexity value is n, then perceived complexity value could be 1.3 * n.If the decision points are more, then complexity of the program is more.

Rule for mcc > 25The steps used to calculate cyclomatic complexity include:
