Object-Oriented C

Object-oriented programming techniques can be approximated in C, despite the language having no built-in classes, by combining structs to hold data with function pointers to simulate methods, often organized as a table of function pointers resembling a virtual method table. Encapsulation is typically achieved through opaque pointers, hiding a struct's internal fields from code outside the module that defines it. This style requires more manual discipline than a language with native object-oriented support, but is common in larger C codebases and libraries.
