Same problem here. int_8 has the same size as char. EOF will not fit in there.
Here is a solution with int (and a little bit shorter):

As GReaper says, it's implementation-defined.

Anyway, EOF is defined as a int and is larger then a char.
If you assign EOF to a char, it will be stipped down to 8 bit.

I have started to think that my wording was incorrect, because I am not a nativ english speaker. ;)

I dont know where you find a contradiction. Both examples uses 'fgetc' and both assign the returned value to a int-variable.

Hmmm, so if you calculate the day of 10th of February (month == 2), you add one day if the year is a leap year.
So 10th of Feb is normaly day 41, but in a leap year it is day 42?
And 1st of March?...

The difference is:
'fgetc' return 'EOF' if there was no character left to read.
'feof' return a value that will be interpreted as 'true' if the eof-flag of the stream is set.
But the eof-flag will...

You should check the input from user.

int days_per_month[] = {31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};

// after the user entered the input in main

// check year

Your comparition will allways be true, because 'c' can't represent EOF.
Look at fgetc - C++ Reference
The function 'fgetc' returns a 'int'.
This means you should declare 'c' as 'int'.

Your compiler should warn you about the print_list() function.
The printf() inside the function has to less arguments.
I have also edited the arguments itself to use the arrow-operator.
