Message: [QUOTE="Daniel T., post: 2544035"] Or better yet... int main( ) { ifstream inf( MOVEX_QUERY ); vector<Document> documents; Document doc; while ( getline( inf, doc.name, ',' ) && getline( inf, doc.edition ) ) documents.push_back( doc ); // do what you will to the documents... } From what I think I know about the OP's problem to solve, a map may make more sense... int main( ) { ifstream inf( MOVEX_QUERY ); map<string, string> documents; string doc; string edi; while ( getline( inf, doc, ',' ) && getline( inf, edi ) ) { if ( documents.count( doc ) == 0 ) documents.insert( make_pair( doc, edi ) ); else cout << "duplicate entry found\n"; // what to do here? } The above will make it easer to compare the edition of a document from this file, to the edition of the same document of the other file.
