many to many CH is well adapted for **square matrix**. Here are the plots of query time of PHAST and many to many CH on assymetric matrix (i.e. number of source and number of target are unequal) with |S| / |T| the number of sources divided by the number of targets : Note th...

A)Additional overloads are provided for all integer types, which are treated asdouble. (since C++11) Parameters num-floating-point or integer value Return value If no errors occur, square root ofnum(√num), is returned. If a domain error occurs, an implementation-defined value is returned ...
在函数print_square中,我们直接使用了cout而没有像上方一样std::cout,省略掉了std,执行结果: the square of 12 is 144 1. 初始化器 int main() { int a{1}; // 使用初始化器,可以有效避免因为类型转换而被强制削掉的数据信息。例如int a {1.2}无法通过编译,而int a=1.2会直接削掉小数部分,a最后等于...
// 不推荐使用宏函数 #define SQUARE(a, b) ((a) * (b)) // 请使用模板函数,内联函数等来替换。 template<typename T> T Square(T a, T b) { return a * b; } 如果需要使用宏,请参考C语言规范的相关章节。 例外:一些通用且成熟的应用,如:对 new, delete 的封装处理,可以保留对宏的使用。
