Hello.. I've been testing fstream libary to read a huge text file (45 megabytes), which has around 2 million lines.. When I do (using fstream): Code: int line = 0; string str; ifstream is("file.txt"); while (!is.eof()) { getline(is, str); line++; }It takes about 9 seconds to read the whole file.. If I open file it with any 'good' text editor (editplus, notepad++ for instance) it takes a few seconds to read/load the whole file.. So I'm wondering.. What am I doing wrong? What should I do to achieve that speed - better preformance? Can boost::iostream do any better? Another thing: I tried writing data to deque (deque.pushback(str)) and was shocked on what happened.. It took ages to process the file, cpu constant at 99% so I closed the program after around 3 minutes.. Whats the 'proper' way to read files to memory? How do text editors do this? They load the same file in 4 seconds! I need a fastest way to read about 10 000 lines from text file at once.. Any help highly appreciated! Best regards A
