Unions in C Language: Techniques for Memory Savings In the C language, a union is a special data structure that allows storing different types of data in the same memory location. Unlike structures, which allocate independent memory for each member, a union only allocates enough space for its largest member. This makes unions an effective … Read more
Programming Virtual Reality and Augmented Reality in C Language In today’s technological era, Virtual Reality (VR) and Augmented Reality (AR) technologies are gradually becoming part of our lives. Although these technologies are often associated with advanced programming languages such as C++, C#, or Python, we can also use the C language to implement some basic … Read more
Arrays in C Language: Usage of One-Dimensional and Multi-Dimensional Arrays In the C language, arrays are an important data structure used to store multiple elements of the same type. They can be integers, characters, floating-point numbers, etc. This article will detail the usage of one-dimensional and multi-dimensional arrays, along with code examples for demonstration. 1. … Read more
1 Object-Oriented C Object-oriented languages are closer to human thinking patterns, significantly reducing code complexity while enhancing code readability and maintainability. Traditional C code can also be designed to be readable, maintainable, and of lower complexity. This article will illustrate this with a practical example. 2 Basic Knowledge 2.1 Structures In addition to providing basic … Read more
