How many millions of lines of code does it take to make the modern program, web service, car, or airplane possible?
The range is extraordinary: the average iPhone app has less than 50,000 lines of code, while Google’s entire code base is two billion lines for all services. And interestingly, the code behind machines such as fighter jets, popular video game engines, and even the Large Hadron Collider fall somewhere in between these two extremes.
Increasing Complexity
A million lines of code, if printed, would be about 18,000 pages of text. That’s 14x the length of War and Peace.
