### how to measure defects per KLOC

I have been reading on the internet about the metric "number of bugs per 1000 lines of code" and what would be a good number. However, I wonder how someone would compute such a metric? The reason a ...

### What is the common practice of calculating average length of identifiers

Quoted from Ian Sommerville's Software Engineering(9th ed), page 673: This is a measure of the average length of identifiers (names for variables, classes, methods, etc.) in a program. The ...

### WMC Calculation in CK Metrics Suite

I have two classes C1 and C2. C1 has 2 methods and C2 has 3 methods each of complexity value 1. C2 inherits from C1. So, I know C2 has 2+3=5 methods in all. The question is, should I take C2 to have 5 ...

### Is measuring the binary size of a c++ program a good indication of code complexity? Or something else?

In my company we have this obligatory practice before a review to be send the binary size impact of the code change to be measured and provided. We must use -Os for this metric to avoid ...

### Why in cyclomatic complexity we add 1 for operators within a condition?

I know that basically, CC can be computed as number of decision + 1. In addition, every logical operator in the condition causes CC to increase by 1. But why? Having the code if(A || B || C) else... ...

### Are there metrics, like in other professions, that can be used to measure whether a programmer is considered experienced? [closed]

Driving instructors (at leas in Germany) often mention 100.000 km driven as a reference point where a driver is considered experienced. Is there a similar number for programmers? For example, how ...

### Codebase Analysis of Trends over Time

I've looked around for a solution (preferably not hosted, something I can run locally) to do static analysis of a codebase over time for things like SLOC, Complexity, authors, commits, etc. It has to ...
