Answer 1

Do not use eof() to determine if you reached end of file. Instead, read what you want to read and then check if you successfully read the data. Obce reading failed you may use eof() to determine if the error is down to having reached the end of the file before producing an error report about a format error.

Since you mentioned that you read that using !infile.eof() is good practice: Can you point us at the source of this wrong information? This information need correction.
