I am puzzled by the output of the code below: std::string content = "abcdefghijklmnopqrstuvwxyz1234567890"; std::istringstream iss(content); iss.seekg(10); std::istreambuf_iterator<char&...

I have implemented a drag-and-drop receiver (C++, WINAPI). It allows me to get a storage with a dragged object (OLE IStorage object). I need to "convert" it to a byte array (something like a ...

I have to write a stream extraction operator>> function which checks if the istream variable (stream) in the parameter is valid before returning it along with a delimiter (which is already ...

So currently working on some exercises on I/O, my code basically takes a string from input and removes the vowels at input: ExerciseClass.cpp: NoVowelString& NoVowelString::operator>>(std::...

My code skipped over the cin under the while loop reading an unknown number of inputs. I wanted to run the code int curval = 0, val = 0; while(std::cin >> curval){ val++; } ...

I am using a library that has a function taking an iostream for a data stream, but I want to pass std::cin. It apparently is not possible to pass an istream to an iostream, but is there way around ...
