1. Introduction: The Mystery of Empty Type Space In the object model of the C++ language, an “empty class”—that is, a type that contains no non-static member variables, virtual functions, or base classes—should theoretically have zero size. However, the C++ standard states: Every complete object must have a unique address. This means that even if … Read more

Introduction In Linux system development, we often need to perform file operations, such as reading configuration files, saving logs, or recording data. The most common methods fall into two categories: One category is System Call I/O: <span>open()</span>, <span>read()</span>, <span>write()</span>, <span>lseek()</span>, etc. The other category is C Standard Library I/O: <span>fopen()</span>, <span>fread()</span>, <span>fwrite()</span>, <span>fclose()</span>, etc. While … Read more

What is a Namespace? A namespace is an important mechanism in C++ for organizing code and avoiding naming conflicts. It allows grouping code elements (such as variables, functions, and classes) into different naming areas, thus preventing name collisions between different libraries or code modules.
