Answer 1

You have a semicolon at the end of your while loop:

while (getline(afile, foo, '\n'));
//                               ^

This causes the extraction to be performed but only the when the loop ends does foo get printed. The last extraction doesn't extract anything which is why foo is empty, hence the empty output.
