fall vector

In practice, the vector series in c ++ -- copy set to vector (do not confuse reserve and resize) The stl algorithm has a copy function. We can easily write this Code: #include #include #include using namespace std;int _tmain(int argc, _TCHAR* argv[]){ double darray[10]={1.0,1.1,1.2,1.3,1.4,1.5,1.6,1.7,1.8,1.9}; vector vdouble(10);

the data has been mistakenly deleted, the first thing to do is to unload the partition of the deleted data, if the data of the root partition is mistakenly deleted, you need to enter the system into single user mode, and the root partition is mounted in read-only mode. Since the file is deleted, only the sector pointer in the Inode node of the file is zeroed out, the actual file is also stored on disk, and if the disk continues to mount in read-write mode, the data blocks of these deleted file

From the source you can see this virus search letter B to Z in the directory, in the three-level directory to find doc/xls/pdf files and copy them to the temporary directory, and then in the documents and Settings or Users directory to repeat the above search. After the search is completed, t

It is also important to note that we use three echoes here, that is, we use three echo statements, and each ECHO statement is followed by a semicolon to indicate that this is a statement, The concep

Believe that each has a practical experience of the SEOR will experience the ranking of Baidu suddenly fall. This drop in rank may be reduced to several pages, dozens of pages, and some even the rankings disappear completely. And more people think that this situation is Baidu K off. In fact, this is just the ranking back, by the spider on the site's recent performance analysis and temporarily do not give a ranking of a study period, but regardless of

The Spring Festival has been smooth over, show to the webmaster is the arrival of spring, the entire annual leave to believe that most of the webmaster also enjoy a good sleep to eat enough of the benefits, although the webmaster have these, but spiders do not necessarily have these. Last night I believe that many of the corporate web site to become hundreds of overnight, this more makes the webmaster heartache, the ranking of the year before, but one night back before liberation. So, today I co

"Eight One Projects" after the fall of love Compared with a man who is in love, a man who is in love is more difficult to pursue another woman. On the one hand, they want to laugh at this woman, and on the other hand, they also need to cope with the pessimistic despair caused by that woman, repair the broken self-esteem, and learn the pursuit skills that have long been unfamiliar. Therefore, after you fall

JDK source code-Vector, jdk-vector1, Vector:-1, an array of objects that can grow. Similar to an object array, it contains an integer index for component access. However, the Vector size can be increased or reduced as needed.-2. Each Vector optimizes storage management by maintaining capacity and capacityIncrement. Cap

Vector applications (element traversal, insertion, deletion, switching, etc.), vectorHere is a summary of some common applications of vector containers. For the vector constructor and initialization, refer to http://blog.csdn.net/lsh_2013/article/details/21191289. Element Traversal Use an iterator to access a vector El
