calculate cyclomatic complexity software testing

It is inversely proportional to code readability and easy to understand code. The recursive call is considered as one functional call otherwise it will create a loop situation that will create a problem to calculate the Cyclomatic complexity for source program.The nodes are internally connected to each other when the next instruction is related to previous instruction.One node is created for one instruction.The use of Cyclomatic complexity can be done for software testing, finding the defects and the correlation among them and limiting the complexity of source code. The flow of the graph is from top to bottom and the bottom node is used for representing the program end. This method uses the graph methodology to finding computer program complexity which can be easily applied for source files of the program, individual functions, and modules of the program. It uses the graphical representation in which the independent paths represent the number of ways in which the computer program can execute. It was given by McCabe for finding the efficiency of a computer program. The complexity of source code can be easily measured. It is the software metric for finding complexity and errors present in the program. The measurement of efficiency of computer programs using the graphical representation method is known as Cyclomatic complexity.

The topological intricacy of the graph can be compared with computer program complexity. The graph notation is used to find a number of ways for the given program and find the complexity of the program. Cyclomatic complexity is a measurement to calculate the code complexity and the errors present in the code using the graph methodology in which nodes of the graph represent source code and the arcs present in the graph represent the control flow in the program.
