My implementation seems to be running almost as fast as raw pointers, which I think is a good sign. What worries me here is why Boost is running slower. Have I missed something in my implementation that is important and I might get into trouble for later? So the idea behind this is ma...
正如Bjarne Stroustrup在《The C++ Programming Language》中所说:“优化是一个双刃剑,它既可以提高性能,也可以增加复杂性。应该在确实需要时才考虑优化。” 5. Pimpl模式的优缺点 (Pros and Cons of the Pimpl Idiom) 深入探究任何技术或设计模式,都会发现它们都有其独特的优势和潜在的弱点。Pimpl模式也不例外。让...

Mappings between pointers and integral types are simply a one to one transfer of bits. No changes to the bits are made. 5.6-4 When dividing two integers with the / operator, where the result is inexact and one and only one of the operands is negative, the result is the smallest integer...
There are several methods to construct a singly linked list. Each is covered in detail below:1. Naive methodA simple solution would be to allocate memory for all individual nodes of the linked list, set their data, and rearrange their pointers to build the complete list....
For that reason, HAMTs implement array mapping Ⓒ: instead of reserving space for n pointers to children in each internal node, the parent node stores a bitmap that indicates which children are present and the actual node only allocates the memory required to refer to its children. This is...
In the double_linked_list_const_iterator class, the Get function that returns a raw pointer is implemented. This method will be necessary for list operations that modify pointers hidden from users within nodes. We make the method protected so that the user of the class cannot call it directly...
Cache line friendly scanning of the correct child by storing edges as two separated arrays: an array of edge chars and one of edge pointers. Complete implementation: Deletion with nodes re-compression as needed. Iterators (including a way to use iterators while the tree is modified). ...
Representation of Trie There are several ways to represent a Trie, corresponding to different trade-offs between memory use and operations speed. The basic form is that of a linked set of nodes, where each node contains an array of child pointers, one for each symbol in the alphabet (so fo...
the string can be represented as an array of characters or using string class that is supported by C++. Each string or array element is terminated by a null character. Representing strings using a character array is directly taken from the ‘C’ language as there is no string type in C. ...
