ifstream duplicate char?

[ajtgarber]

I have a program that reads in a file character by character, and for some reason the last character is always duplicated. I'm thinking that maybe I'm messing up my loop or something.

The file (testfile.txt):

Code: Select all

test test test

The code reading the file:

Code: Select all

if(file.is_open()) {
            string str;
            while(!file.eof()) {
                 char c;
                 file.get(c);
                 cout << c;
                 
                 if(c != ' ' && c != '\n' && c != '\r')
                      str += c;   
                 else {
                     Token token(str);
                     tokens.push_back(token);
                     str = ""; 
                 }          
            }
            if(str.size() > 0) {
                Token token(str);
                tokens.push_back(token);              
            } 
}

the output always ends up being:
test test testt

You've misunderstood what eof does. Look here for the correct way to use get in a loop.
