OOP was invented because procedural languages, such as C, Pascal, and BASIC, were found to be inadequate for large and complex programs. Why was this?

Groups of functions could form larger units called modules or files. Crude Organizational Units One difficulty with this kind of function-based organization was that it focused on functions at the expense of data. There weren’t many options when it came to data。
