Deep Understanding of Exception Class Hierarchy The C++ Standard Library provides a rich set of exception classes that form a hierarchy. std::exception is the base class for all exception classes, defining a virtual function what() to return a string describing the exception. For example: #include <iostream> #include <exception> int main() { try { throw std::exception(); … Read more
In the world of C++ programming, resource management has always been a headache, especially when dealing with memory, file handles, and other system resources. Today, I want to explore a very important concept with you—RAII (Resource Acquisition Is Initialization). Through this article, you will understand how RAII helps us manage resources effectively, avoiding common memory … Read more
In C++, resource management is a very important topic, especially when it comes to managing system resources such as memory, files, and network connections. C++ provides powerful tools and features to help programmers manage these resources efficiently and safely, with one of the key techniques being the application of smart pointers.

Don’t worry, it’s quite simple! 1 Let’s Talk About the Characteristics of Embedded Development Embedded development … Read more
C++ exception handling is one of the important features for improving program robustness and maintainability. In C++, resource management is closely related to exception handling, especially in ensuring that resources are correctly released in the event of an exception. In this regard, RAII (Resource Acquisition Is Initialization) is a very important design pattern that uses … Read more
