This two weeks of study, I feel a little hard, in terms of function is not very clear, especially in the reference to the function of their own when the format is always incorrect, resulting in the text can not be quoted, and the content of the book

Through Rtti, it is possible to pass the base classpointer or referenceTo retrieve the actual type of the object it refers to. C + + provides RTTI by using the following two operators. (1) typeID: Returns the actual type of the object that the

The construction of binary tree should pay attention to the difference with the chain table, the binary tree here is very low-level, each tree just constructs a single two-fork tree node, the overall view is the next upward build. Users need to

Given a sorted array, remove the duplicates in place such, all element appear only once and return the new length. Do the allocate extra space for another array, and you must does this on place with constant memory. For example,given input Array

String copy on write: After assigning the string str1 to Str2, str2 and str1 share memory unless STR1 's content has been changed. When STR1 is modified, STL opens up memory space for str2 and initializes it.　　#include

Job A:1. Write the function int oddsum (int n) to calculate all the odd numbers in n integers and. The value of the n number is entered by the user from the keyboard.#include intMain () {intn,i,a,sum=0; printf ("you need to enter several numbers:");

Static linked lists facilitate the use of linked list structures in high-level languages without pointer types, static linked lists are described by arrays, one component of an array represents a node, and a cursor (indicator cur) is used instead of

So how do we compare pair by value? The first kind: is the most primitive method, write a comparison function, the second kind: just used, write a function object. Both of these approaches are relatively simple to implement. typedef pairint>

JS Novice recently in the study of JS data structure, just see the linked list to achieve this together, feel some information and their understanding of conflict, so through their own before a little C language foundation, with JavaScript imitation
