How to Read from a Text File, Character by Character in C++

Question

I was wondering if someone could help me figure out how to read from a text file in C++, character by character. That way, I could have a while loop (while there's still text left) where I store the next character in the text document in a temp variable so I could do something with it, then repeat the process with the next character. I know how to open the file and everything, but temp = textFile.getchar() doesn't seem to work. Thanks in advance.

You could try something like:

char ch;
fstream fin("file", fstream::in);
while (fin >> noskipws >> ch) {
    cout << ch; // Or whatever
}
