Implementing Queues in C: Sequential and Linked Queues In computer science, a queue is a very important data structure. It follows the “First In, First Out” (FIFO) principle, which means that the earliest added element will be the first to be removed. This article will introduce how to implement a queue in C, including both … Read more
Inline Functions in C: Enhancing Performance In C, functions are an important way for us to encapsulate code and achieve reuse. However, in certain cases, calling a function may incur some performance overhead. To address this issue, C provides a very useful feature—Inline Functions. This article will explain in detail what inline functions are, how … Read more
Modular Design of C Language Code: Enhancing Maintainability In software development, especially when programming in C, modular design is an important method for improving code maintainability. This article will explore what modular design is and its significance, while demonstrating how to implement modularity in C through examples. What is Modular Design? Modular design is a … Read more
Implementing Network Programming in C: TCP/IP Protocol In today’s era of the internet, network programming has become an increasingly important skill. The C language, as a crucial tool for system-level programming, is widely used to implement various network applications. In this article, we will explore how to use C for network programming with the TCP/IP … Read more
String Handling Functions in C: strlen, strcpy, and More In C, strings are stored as arrays of characters and are terminated by a null character <span>'\0'</span>. To facilitate the manipulation and processing of strings, the C standard library provides a series of string handling functions. In this article, we will detail several commonly used string … Read more
Error Handling in C: Elegant Exception Management In programming, errors are inevitable. No matter how careful we are, we will always encounter various issues, such as file not found, network connection failure, etc. In C, a low-level programming language, although there is no built-in exception handling mechanism (like the try-catch syntax in C++), we can … Read more
Implementing Bubble Sort in C: Principles and Optimizations Bubble sort is a simple sorting algorithm that works on the principle of repeatedly traversing the list to be sorted, comparing adjacent elements and swapping their positions, thereby allowing larger elements to “bubble” to the top of the list. Although it has a high time complexity (O(n^2) … Read more
Implementing Graphs with Adjacency Matrix and Adjacency List in C In data structures, a graph is a very important model that can represent various relationships, such as social networks, maps, and transportation networks. Graphs can mainly be represented in two ways: the adjacency matrix and the adjacency list. This article will detail these two representation … Read more
📌 Problem Description Write a program to output a standard 9×9 multiplication table with the following requirements: Present in astaircase alignment format Allow the user to input n and output an n×n multiplication table Advanced: Implement with the least amount of code (testing code simplification ability) Example output: 1×1=1 1×2=2 2×2=4 1×3=3 2×3=6 3×3=9 … … Read more
Company coding standards prohibit the use of unsafe functions and require the use of custom safe functions developed internally. In C language, some functions are not absolutely safe, such as memcpy which may have overlapping memory regions; strcpy, gets, and sprintf do not check the size of the target buffer; and scanf series (which do … Read more
