How software quality is measured?

Quantitative quality metrics measure

how big or complex the software program

is, the number of lines and functions it contains, how many bugs there are per 1,000 lines of code, and more. Qualitative code quality metrics measure features like maintainability, readability, clarity, efficiency, and documentation.
