Using profiler to analyze the performance of code is more efficient, detailed, and intuitive than pure cognitive analysis.

In C++, when the operand types of an operator are inconsistent, these operands will be converted to the same type. Type conversion is divided into implicit conversion and explicit conversion.

近期准备求职面试。
将C++中面向对象部分的基础知识复习整理一下。

When designing classes to overload operators, it is essential to choose whether to implement the operator as a member or as a regular non-member function.

In the process of solving problems, I came across this code snippet for formatting output: printf("%*s%s%*s\n",__________);
The required output format is: ________123456________//The underscores represent spaces

When writing code, the macro (#define) command is often used. Recently, I encountered two instances where macros were misused, so I’ll analyze them here.

As a C++ programmer, I have long been accustomed to using tools like GCC, but I must say that GCC’s error messages are terrible. Although there are error prompts, it often requires manual debugging to understand them… Now, the good news is here, the accuracy of Clang‘s messages is incomparably better than that of GCC.

Actually, using WolframAlpha to compute integrals is quite overkill (but it’s also a strict requirement for laziness). Recently, I’ve been studying Wolfram Language and slowly discovering new ways to play with it.

Previously, I would complete articles on local and then publish them, having already set up a bunch of things like node.js, hexo, git, etc. on my own computer. So, it’s very convenient to use on my computer, but if I switch to another computer, it’s tragic; everything needs to be configured by myself, so I almost end up in a non-usable state whenever I change computers.
