EOF = End of File

 

So basically that program is just reading from STDIO (ie: console),  and will keep reading until it encounters "\n" (which has a specific meaning in C), or the EOF symbol.  Hence, "flushing input".

 

getchar() is just like getc(), instead it defaults to reading from STDIO instead of taking a file descriptor.

yeah you made it even more confusing sorry i really didn't get your explanation cause i'm new her so please take your time with me and put all the details 

i have a buffer problem with a char string so i need to find the \0 not the eof or even the \n what have they to do her in the first place why ? thanks for your time

/0 is for null terminated string. Basically it is a null character at the end of the string to show the end of the string. Without it the length of the string would border on the infinite.

If you don't understand the code in the OP, you need to get a better tutorial, as it's apparently glossing over a lot of important concepts.

\n  is new line  (one of the two characters that are introduced in files when you press ENTER)

Traditionally enter is CRLF , carriage return and life feed (advance on text line and reposition the cursor at the beginning)

 

EOF is end of file,

In the DOS days, it was also a character ... see https://en.wikipedia.org/wiki/End-of-file

You would press Ctrl + Z to close a file ... you can still do this in the command prompt: COPY CON file.txt    CON is a special keyword for console, the command prompt window, so the command will copy anything you type in the console window into the file, until you press Ctrl+Z
