Which one is measure of software complexity?

The correct answer is option 4.

Concept:

Option 1 (Number of lines of code) and Option 3 (Number of function points) are measures of software complexity, while Option 2 (Number of man years) is not typically considered a measure of complexity but rather a measure of development effort. Therefore, the correct answer is option 4: all of the above.

• The Number of Lines of Code (LOC) measures the size of the program, and a larger codebase can be more complex to maintain and understand. However, LOC does not take into account the quality or efficiency of the code.

• Function Points (FP) is another metric used to measure the size and complexity of a software system, which focuses on the functionality provided by the system. FP considers the number of inputs, outputs, inquiries, files, and interfaces involved in the system.

• While man-years can be used as a measure of development effort, it does not necessarily indicate the complexity of the software. A small software project can still require many man-years of effort if the development team is small, inexperienced, or working with difficult technologies.
