c++ - Multiple use of same file streaming object -

i've written following source code:

ifstream leggifile; leggifile.open("questions.txt",ios::in);  if (!leggifile.good()) {   cerr << "\n\n\n\terrore during file opening questions.txt\n\n\n" << endl; } else {     // ... };  leggifile.close(); system("pause"); 

now i'd use same object working second file.

leggifile.open("answers.txt",ios::in);  i=0; if(!leggifile.good()) {   cerr << "\n\n\n\terror during opening of file answers.txt\n\n\n" << endl; } else {     // ... } 

problem: 2nd time file cannot opened , error message appears. why? please suggest me solution?

it's possible you've done work on stream set 1 or more of error flags, such eofbit.

closing stream doesn't clear error flags, have manually. call leggifile.clear(); after close it.

since c++11, done automaticaly open(), though. if you're using c++11 compiler, problem elsewhere (can't where, haven't shown enough code).
