// 整合成一个类模板实现,看着好,但引入了 代码膨胀 template<int n> class IntBubbleSortC { template<int i, int j> static inline void IntSwap(int* data) { // 比较和交换两个相邻元素 if(data[i]>data[j]) std::swap(data[i], data[j]); } template<int i, int j> static inline void...
Lisp has the most sophisticated and complete support for compile-time metaprogramming, through its system of macros. Unlike C macros that have limited expressive power and that operate based on textual substitution, Lisp macros are powered by the full extensibility of the language. JAVA : ANNOTATION...
Imagine if you could have computer programs that wrote your code for you. It is possible, but the machines will not write all your code for you! This technique...
此示例显示了使用模板元编程计算功率的有效方法。 template <int base, unsigned int exponent> struct power { static const int halfvalue = power::value; static const int value = halfvalue * halfvalue * power::value; }; template <int base> struct power { static const int value = 1; static...

Careful tuning of code is crucial to obtain near-optimal runtime performance on the hardware at hand. How-ever, current hardware platforms pose plenty of challenges: multiple levels of cache, many cores and increasingly wider vector units render manual tuning time-consuming and cumbersome. Thus, ...
A C variant is hosted here; I will complete it when this library is feature complete, it should be easier to make than this... Usage A metaprogram is built to generate files before the main program is built. We'll term runtime for this program as GEN_TIME. The metaprogram's core ...
The success of learning objects (LO) is limited by the ability to integrate them into coherent teaching courses in order to enable the educational goal-oriented creation of competency. LO sequences must be defined that are adapted to different types of learners, their personal needs and knowledge...
