The reported versions of gcc don't recognize whitespaces. This behavior prevents streams from reading strings word by word. Thereby, the whole data gets readed if a string is retrieved from the stream.(eg. cin >> myString;) bool ParseFile(const char* fileName) { if( !fileName ) return false; ifstream inFile( fileName ); if( !inFile ) return false; inFile >> noskipws; char aChar; while( !inFile.eof() ) { inFile >> aChar; cout << aChar << "["; if( isspace( aChar, inFile.getloc() ) ) cout << " true ]" << endl; else cout << " false ]" << endl; } inFile.close(); return true; } >How-To-Repeat: The main program is this one: int main(int argc, char* argv[]) { cout << "Result: " << ParseFile( argv[1] ) << "." << endl; return 0; } Compile with: g++ -ggdb -o runMe main.cpp Run with: runMe [your_text_file] >Fix: None that i know. >Release-Note: >Audit-Trail: >Unformatted:
