Hi rooters,
I have some problems using fstream in the root script.
My root ver. is 3.02/07. linux redhat 6.1.
The probrem is that next script test.C doesn't work well.
-----test.C----------
{
ifstream fi("test.dat");
cout << fi.is_open() << endl;
string t;
fi >> t;
cout << t << endl;
}
The error output is
root[1] .x test.C
==> ifstream::is_open () in current scope FILE:test.C LINE:3
==> Possible candidates are...
==> Possible candidates are...
==> filename line:size busy function type and name (in ifstream)
==> filename line:size busy function type and name (in fstreambase)
==> filename line:size busy function type and name (in ios)
==> filename line:size busy function type and name (in istream)
==> filename line:size busy function type and name (in ios)
==> *** Interpreter error recovered ***Possible candidates are...

So I commented out the line of cout << fi.is_open() << endl;
-----test.C----------
{
ifstream fi("test.dat");
//cout << fi.is_open() << endl;
string t;
fi >> t;
cout << t << endl;
}
but it said
root[1] .x test.C
==> Error: Symbol i is not defined in current scope FILE:bstring.h LINE:2523
==> Error: Failed to evaluate i.operatorvoidError: Binary operator oprand missing FILE:bstring.h LINE:2523
==> *** Interpreter error recovered ***
