C++ detecting end of file

Question

I have a C++ program that is reading in info from a file, that stores info seperated by "$$$$". An example of how the file looks is:

abc
bcd
$$$$
def
$$$$
qwe
gfh
$$$$

How can I detect the file has ended, without using the eof() function?

I have it set like this,

getline(sin,temp)
if (temp=="$$$$")
{
}

After reading the last set of four dollars, how can I check the next line to ensure another set of data isn't beginning, and that the file has ended? If the file has indeed ended, I plan on using a boolean flag to terminate the while loop.

Answer 1

I'm not sure why you can't use eof() but you could get the file size first and then only read that many bytes.

Answer 2

while (getline(sin, temp))
{
    // use temp.
}

You will come out of loop once you are end of file.
