如何检测C中的空文件？

if (inputFile.fail()) //check for file open failure
{
    cout << "Error opening file" << endl;
    cout << "Note that the program will halt" << endl;//error prompt
}

else if (inputFile.eof())
{
    cout << "File is empty" << endl;
    cout << "Note that program will halt" << endl; // error prompt
}
else
{
    //run the file
}

它使用此@L_607_2@无法检测到任何空文件.如果我使用inputFile.peek而不是eof,它会将我的好文件作为空文件.
