Learning the Rust Programming Language

Object-Oriented Programming (OOP) is a way of modeling programs. The concept of an object originated from the Simula programming language in the 1960s. These objects influenced Alan Kay’s programming architecture, where objects communicate by passing messages to each other. He coined the term “object-oriented programming” in 1967. There are many conflicting definitions of what OOP … Read more

Application Example of the Observer Pattern in C Language Projects

Application Example of the Observer Pattern in C Language Projects The Observer Pattern is a behavioral design pattern that defines a one-to-many dependency between objects, so that when one object (the subject) changes state, all its dependents (the observers) are notified and updated automatically. This pattern is widely used in event handling systems, GUI frameworks, … Read more
