This section of the article: Understanding Template meta-programmingThis section of the article is a brief introduction to template metaprogramming, which allows the reader to know that there is a way of programming, rather, a technique.So, what is

1. Programmer's Explicit memory releaseFor C + + programmers, the most mind is to manage the dynamically allocated memory. C + + allocates memory on the heap, requiring the programmer to dispose of the allocated memory. But sometimes the release of

We all have to realize that writing a program is actually a matter of delicate work.In the beginning, my code is probably like this:class B; class a{public: A () {} A (int A): ID (a) {} private : b b; }; class public: B () {} B (int b):

Today, I'll talk about naming rules in C + +.Naming conventions or naming restrictions can be applied to function naming, variable naming, constant naming, struct naming, custom type naming, and class naming in C + +, object naming, template class
