1、The  Bit  interface exports functions that manipulate bit vectors, which can be used to represent sets of integers from zero to  N− 1. For example, 256-bit vectors can be used to represent sets of c

1、A ring  is much like a sequence: It holds N values associated with the integer indices zero through N −1 when N is positive.  2、An empty ring holds no values. Values are pointers.  3、Like the valu

1、A sequence holds  N  values associated with the integer indices zero through N−1 when  N is positive.  2、An empty sequence holds no values.  3、Like arrays, values in a sequence may be accessed by

1、An  array  is a homogeneous sequence of values in which the elements in the sequence are associated one-to-one with indices in a contiguous range.  2、Arrays in some form appear as built-in data typ

1、A set is an  unordered collection of distinct members.  2、The basic operations on a set are testing  for membership, adding members, and removing members.  3、Other operations include set union, in

1、An  associative table is a set of key-value pairs. It’s like an array except that the indices can be values of any type. C语言中宏的作用域是文件或者遇到undef为止。 table的实现是以哈希表和链表实现。内存形式如下： ==========

单链表的原理不在赘述！ 通过优美的源代码进行理解其中的道理！ ======================list.h========================= #ifndef LIST_INCLUDED#define LIST_INCLUDED#define T List_Ttypedef struct T *T;struct T{T rest;void *first;}

1、This chapter describes a memory-management interface and an imple-mentation that uses arena-based algorithms, which allocate memory from an arena and deallocate entire arenas at once. 2、With the ar

1、After the call to  free,  p  holds a dangling pointer— a pointer that refers to memory that logically does not exist. Subse-quently dereferencing p  is an error, although if the block hasn’t been re

原文 说明: 因为图片无法下载，我们就看看结论吧。 介绍 在相当多的应用程序中，我们必须处理稀疏数组或具有整型键的映射。当元素的数量相当少 (比如不超过1000个) 时，使用标准的std::map或std::unordered_map就足够了。当键的数量增加时，这些映射的表现就不那么好了: 我们想要考虑更快的容器。在本文中，我将尝试研究使用整数键实现映射并度量其性能的各种方法。 该代码在
