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
