    //When read pointer reads the # it will exit loop
    //This requires that you have a # sign as last character in your text file

    while (singleCharacter != END_OF_FILE)
    {
         cout << singleCharacter;
         inFile.get(singleCharacter);
    }

   //If you need to store each character, declare a variable and store it
   //in the while loop.

To quote Bjarne Stroustrup:"The >> operator is intended for formatted input; that is, reading objects of an expected type and format. Where this is not desirable and we want to read charactes as characters and then examine them, we use the get() functions."

char c;
while (input.get(c))
{
    // do something with c
}
