The document discusses the limitations of procedural programming languages and how object-oriented programming (OOP) addresses these limitations. Specifically, it notes that procedural languages have issues with unrestricted access to global data and modeling real-world objects which have both attributes and behaviors. OOP combines data and functions that operate on that data into single units called objects, encapsulating the data and hiding it from direct access. This solves the problems of procedural languages by restricting access to data and more closely modeling real objects.
