Error handling is a crucial part of programming. Although the C language does not have a built-in exception handling mechanism, we can still implement effective error management through various methods. This article will detail error handling in C and common practices, providing code examples to aid understanding. 1. Types of Errors In C, there are … Read more
Building and Searching a Binary Search Tree in C Language Introduction A Binary Search Tree (BST) is a special type of binary tree that has the following properties: Each node has a value. For each node, all values in its left subtree are less than the value of that node. For each node, all values … Read more
String Handling in C: Character Arrays and String Functions In C, strings are not a distinct data type but exist as character arrays. Understanding how to use character arrays and related string functions is crucial for writing effective C programs. This article will provide a detailed overview of string handling in C, including the definition … Read more
In multi-process or multi-thread programming, file read and write operations may lead to data inconsistency. To avoid this situation, the C language provides a file locking mechanism to control access to the same file. This article will detail the file locking and file sharing mechanisms in C language and demonstrate them through code examples. Basic … Read more
In the development of embedded systems and operating systems, interrupts are an important mechanism. They allow programs to respond immediately to specific events without the need to constantly poll device status. This article will provide a detailed introduction to interrupt handling in C language and its related concepts, suitable for beginners to learn. What is … Read more
In operating systems, task scheduling is a crucial concept. It determines how multiple processes or threads share CPU resources. In this article, we will introduce two common task scheduling algorithms: Round Robin Scheduling and Priority Scheduling. We will demonstrate the implementation of these two algorithms through C language code examples. 1. Round Robin Scheduling 1.1 … Read more
Project Management in C Language: Version Control and Documentation Management In software development, especially when developing projects using the C language, effective project management is a crucial factor in ensuring code quality and team collaboration. This article will introduce two key aspects of project management: version control and documentation management, along with corresponding code demonstrations. … Read more
Unit Testing Methods and Practices in C Language In software development, unit testing is an important testing method used to verify the correctness of the smallest testable units in a program (usually functions or modules). This article will introduce unit testing methods and practices in C language, helping basic users understand how to write and … Read more
Problem: Example 066 Problem: Input three numbers a, b, c, and output them in order of size. Program Analysis: Use pointer method. NEXT Solution: # include<stdio.h> void swap(int *, int *); int main(void) { int a, b, c; int *p1, *p2, *p3; printf(“Input a, b, c:\n”); scanf(“%d %d %d”, &a, &b, &c); p1 = &a; … Read more
