Introduction
In the realm of software development, the complexity and scale of an application can often be measured by the number of lines of codes (LOC) it contains.
Each line represents a piece of functionality, a part of the user interface, or a backend process working behind the scenes.
Here, we break down the LOC (lines of codes)of various well-known software and hardware systems to give you an idea of the intricacies involved in creating these modern marvels.
