Principles of Quick Sort and Merge Sort in C Language In computer science, sorting algorithms are fundamental knowledge. Today, we will provide a detailed introduction to two commonly used sorting algorithms: Quick Sort and Merge Sort. Each of these algorithms has its advantages and disadvantages, making them suitable for different scenarios. 1. Quick Sort 1. … Read more
Memory-Mapped File Operations in C Language A memory-mapped file is a technique that maps the contents of a file directly into the process’s address space. This allows the program to access file data as if it were accessing memory, thereby improving I/O efficiency. In C language, we can use the mmap function to perform memory-mapped … Read more
The Clever Use of if and switch Statements in C Language In C language, selection structures are important tools for controlling the flow of program execution. They allow the program to execute different blocks of code based on different conditions. This article will detail two commonly used selection structures: <span>if</span> statement and <span>switch</span> statement, and … Read more
#includeIn C language, #include is a preprocessor directive that is used to include the contents of another file into the current file before compilation. In simple terms, it acts like copying and pasting the contents of the specified file at the location of#include.Its core function is toinclude header files, allowing the code to access functions, … Read more
Code Standards and Commenting Guidelines in C Language When writing programs in C, good coding standards and commenting practices not only improve code readability but also facilitate team collaboration and future maintenance. This article will detail some basic coding standards and commenting guidelines in C, illustrated with examples. 1. Code Formatting 1. Indentation Using a … Read more
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
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
01Introduction: In C language, break, return, and continue are three completely different control statements, with the following specific differences: 02Break 1. Usage Scenarios Loop statements (<span><span>for/while/do-while</span></span>） and <span><span>switch</span></span> statements. 2. Core Functionality In loops: Immediately terminate the entire current loop and continue executing the code after the loop. In switch: Exit the<span><span>switch</span></span> structure to avoid … Read more
Shocking! C Language Can Achieve Object-Oriented Programming: Principles and Examples Fully ExplainedCan C Language Achieve Object-Oriented Programming? Introduction Object-Oriented Programming (OOP) is a programming paradigm centered around “objects,” organizing code through features such as encapsulation, inheritance, and polymorphism. While languages like C++ and Java natively support OOP, C, as a procedural language, can also achieve … Read more
