Hi, I am trying to read a whole file in, but apparently using eof() doesn't seem to work. For example, when I have something like this:
ifstream input_file(argv[1], ios::in);
while (!input_file.eof())
cout << "hello?";
This continuously prints out "hello?" which means that the end of the file is not being found. Any suggestions would be appreciated. The input file, by the way, has 15 characters in it.
Thanks in advance.
This should work:
havn't tested it. Just came up with it. Hope this helps.Code:#include <fstream.h> #include <iostream.h> int main(void){ char str[600]; //string array of 600 ifstream file; file.open("C:\\test.txt"); while (!file.eof())//the end of the file(eof) { file.getline(str, 90); cout << str << endl; } file.close(); //close the file return(0); }
I tried your example...it also seems to be running in an infinite loop... =(
I am using MS Visual Studio and don't understand why it doesn't work...seems simple enough, doesn't it?
Thanks for your help though.
>ifstream input_file(argv[1], ios::in);
>while (!input_file.eof())
>cout << "hello?";
This does nothing to move the file pointer toward EOF, so of course it is an infinite loop, the file pointer doesn't move. If you input data inside the loop then it should work a bit better.
-PreludeCode:while ( input_file.good() ) { input_file.get(); cout<<"Hello?\n"; }
My best code is written with the delete key.
Yes you are right. I am sorry. I initially left out the details of the loop to make it simpler.
This is the actual loop I tried:
while (!input_file.eof())
{
input_file.getline(buffer,MAX_BUF-1);
input.push_back(buffer);
}
Thanks.
