iostream

Can I open an ifstream (or set an existing one in any way) to only read part of a file? For example, I would like to have my ifstream read a file from byte 10 to 50. Seeking to position 0 would be position 10 in reality, reading past position 40 (50 in reality) would resualt in an EOF , etc. Is this possible in any way? It definetly can be done by implementing a filtering stream buffer: you would derive from std::streambuf and take the range you want to expose and the underlying stream buffer (well, a pointer to it) as arguments. Then you would seek to the start location. An overridden

I've never been much to use C++ I/O streams and have always opted for what I know. i.e. the printf functions. I know there are some benefits to using I/O streams, but I'm looking for some tips from the stackoverflow community to help me (or convince me) to switch. Because I still prefer printf and I think the printf style is so much easier to read and quicker to type. I would still like to be familiar with it even if I still continue to use printf. Edit. Interestingly, google C++ coding style forbids the use of streams except for logging. See: http://google-styleguide.googlecode.com/svn/trunk

In C++ we always put the following at the top of the program #include <iostream> What about for C? AraK Well, this is called the standard I/O header. In C you have: #include <stdio.h> It's not an analog to <iostream> . There is no analog to iostream in C -- it lacks objects and types. If you're using C++, it's the analog to <cstdio> . stdio man page GNU documentation on Input/Output on Streams See also this fantastic question and its answer, 'printf' vs. 'cout' in C++ #include <stdio.h> iostream is a C++ library for input-output. The C equivalent would be stdio.h #include <stdio.h> C Standard

This question already has an answer here: redirect std::cout to QTextEdit 2 answers I'm new to Qt application development, I would appreciate your help. This is a re-post of redirect std::cout to QTextEdit I'm trying to redirect std::cout to a QTextEdit and I've seen and tried to test the example provided in the following link. Reference Link 1: http://lists.trolltech.com/qt-interest/2005-06/thread00166-0.html Using Qt Creator 2.4.1 to test the example from Reference Link 1. untiled1.pro SOURCES += \ main.cpp HEADERS += \ qdebugstream.h qdebugstream.h #ifndef QDEBUGSTREAM_H #define

I have a C++ class " X " which would have special meaning if a container of them were to be sent to a std::ostream . I originally implemented it specifically for std::vector<X> : std::ostream& operator << ( std::ostream &os, const std::vector<X> &c ) { // The specialized logic here expects c to be a "container" in simple // terms - only that c.begin() and c.end() return input iterators to X } If I wanted to support std::ostream << std::deque<X> or std::ostream << std::set<X> or any similar container type, the only solution I know of is to copy-paste the entire function and change only the
