C++

C + + and C language, there are pointers, pointers through the storage location of variables to access the contents of the variable and modify, unlike the reference is simply to give the variable an alias, not an object, and the pointer is an object.

Array object arrays have a sort method (click to see the implementation of the Sort method), specifically for sorting, seeIf we want to add a sort to our class, we just need to inherit the IComparable interface and implement the CompareTo

Transferred from: http://blog.sina.com.cn/s/blog_679f85d40100mysi.htmlLet's talk about the function of fseek () in C language:function prototypes: int fseek (FILE *fp, LONG offset, int origin)Parameter meaning: FP file pointer offset relative to

Joseph Ring problem can be implemented simply by using arrays, but now I use a circular link list method to achieve, because I see a question in the morning to use a circular list to solve the problem of Joseph Ring.What is Joseph Ring?Joseph Ring

1, two iterators are composed of an interval of the front closed after the open2. If the iterator is valid, the iterator will fail if the element pointed to by the iterator has been deleted.http://blog.csdn.net/hsujouchen/article/details/89872333,
