I want to retrive the data from the end in a map.
Generally for retriving we write below code for getting data from begining.
so please suggest how can we get the data from the end in a map???
map<int,cstring>::iterator itera;
for(itera = m_mapFinalSortVirusData.begin();itera != m_mapFinalSortVirusData.end();itera++)
{
int nCount= itera->;first;
CString strvirname = itera->;second;
CString str = "";
str.Format("%d %s",nCount,strvirname);
AfxMessageBox(str);
}

Not exactly correct: when iterating in reverse mode, you should replace the usual begin() by rbegin() and the usual end() by rend(). Thus rend doesn't return you the last element in your map but point before the first element.

Check out the example in the linked page.

Use a reverse iterator: it is the same principle as an iterator, except that it starts from the end of the container. You have to use the rbegin function (which returns the begining of the reverted map, aka the end of your original map).

What about something like:
itera = m_mapFinalSortVirusData.end();
itera--;
int nCount= itera->first;
CString strvirname = itera->second;

Hello brucewayn,
Is your logic dependent on the order of inserted items in map? I just want to tell you that, unlink other containers such as vector, list etc, there is no order for the inserted item in map. So be careful.
Regards,
Jijo.

How to calculate total line number of a text file?
I have a text file. I want to get the total line number of it. Could somebody know which function should I use? Or I should write the counting code for each line?

You could open the file and read each character to see if it is a newline. This is not very efficient because of disk I/O but it will handle very large files. You could also read the entire file into a buffer and then read through the buffer counting newline characters. This is more efficient because disk I/O is done once, but it will not handle very large files. There are also functions that will read lines from files (they know internally to read to the next newline) so you could just count how many times a line is read.

Or he could do the "inbetween" solution, create a buffer of some size and read as much of the file into it as he can, start counting and when he runs out of the buffer he can read more of the file in and continue with the same buffer starting from its beginning. This is much much much faster than reading char by char or line by line even, it will handle large files, but it won't eat up every bit of memory it finds hanging around the data bus "just chillin', wathching the game, having a beer".

You need to read line by line on the text files.

You could try this:
std::ifstream myFile("a.cpp");
int count = 0;
std::string s;
while (std::getline(myFile, s))
++count;
although I suspect this (counting the line-feed characters in the file) is slightly better:
std::ifstream myFile("a.cpp", std::ios::binary);
myFile >> std::noskipws;
std::cout << 1+std::count(std::istream_iterator<char>(myFile), std::istream_iterator<char>(), (char)10) << std::endl;
