getline reads one line too much
Hi,
so I want to read a text file line by line, so that each row should be stored in a string. The text file looks like this:
name1;phone_number1;address1
name2;phone_number2;address2
... |
So I wrote the following function:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
|
void filereader (char * location) {
string aString;
ifstream inputstream;
inputstream.open(location, ios:: in);
if(inputstream){
while(!inputstream.eof()){
getline(inputstream, aString);
cout <<"getline: \""<< aString << "\"" <<endl; // testing
}
}
else{
cout <<"file not found!" <<endl;
}
inputstream.close ();
inputstream.clear ();
}
|
Unfortunately, the program is reading one line too much and the output is looking like this:
"name1;phone_number1;address1"
"name2;phone_number2;address2"
"" |
At first I thought it was a "\n" or "\0". That's why I added an if statement ..
1 2
|
if (aString != "\n")
cout << "getline: \"" << aString << "\"" << endl;
|
.. it doesn't wordk.
How can I avoid this superfluous string?
I'm using Netbeans + Ubuntu
Thanks in advance

You need to check for eof after reading aString, the last input operation will always fail
Wow that's worked! Thank you very much.
