C++: Parse input skipping whitespace
Spanish version / Versión en Español Still re-reading Stroustrup's book , I found something I'd like to have known some time ago: an elegant way to parse an input stream for words separated by whitespace (1 whitespace = any amount of consecutive space and/or tabs). This can be done using an istream_iterator, like so: #include <fstream> #include <iostream> #include <algorithm> #include <vector> void main(){ using std::cout; using std::endl; // We read from standard input, but it could just as well be a file std::istream_iterator<std::string> ii( std::cin ); cout << "--->Input whitespace-separated words:" << endl; // Suppose we stop reading when we find the word "END" std::vector<string> words; while ( *ii != "END" ){ cout << *ii << endl; words.push_back(*ii); ii++; } // Sort words cout << "Sorted words:...
