Is there any if statement to check if a file is empty? |

You can probably just check the file's size or length against 0. If it's 0, the file is empty, otherwise not. I don't know how you'd find the length of a file in C++ offhand though. |

I believe you can do this using istream::peek(), which returns the value of the next character in a file, but leaves it as the next character to be read. open a file, peek(), and if it returns EOF, your file is empty. |
