博客给出C++编程的实用建议，如类若需自定义拷贝构造函数、拷贝赋值运算符或析构函数，可能三者都需；避免硬编码，数据成员设为私有；写有用注释，遵循const正确性，避免类型切换，不用下划线开头命名，可用boost::any表示变体类型。

If a class needs a custom copy constructor, copy assignment operator, or destructor, it probably needs all three.

Avoid hard-wiring information that needlessly makes code more brittle and limits flexibility.
Always make all data members private. The only exception is the case of a C-style struct which isn't intended to encapsulate anything and where all members are public.
Write (only) useful comments. Never write comments that repeat the code; instead, write comments that explain the code and the reasons why you wrote it that way.
Practice const-correctness
Avoid type switching; prefer type safety
Never use "underhanded names"—ones that begin with an underscore or that contain a double underscore. They are reserved for your compiler and standard library implementation.
If you want to represent variant types, for now prefer to use boost::any (or something equally simple).
