where you opened the file?

Nithin Sundar 1-Jun-11 7:27am

Wait a sec.....EOF is used to check for end of file. You are checking EOF for a....integer variable?

OriginalGriff 1-Jun-11 7:31am

Check the definition: EOF is #defined as -1
It's not good practice, but it will work.

Nithin Sundar 1-Jun-11 7:32am

Ah alright Thanks! The way he's using it is very misleading. :O

Why do you use EOF in the first place?

Try typing a CTRL+Z: if that doesn't work, try CTRL+C, but that may just kill your app.

The question edit notes you added were hilarious.

OriginalGriff 1-Jun-11 7:33am

Blasted things! Now that pre tags allow gt and lt symbols to work without being taken and consumed as tags, the "let's not have badly formed HTML to mess up the page" checking adds close tags for stdio.h and so forth - which not appear in the preview, but do in the post. Grrrrr!

Nithin Sundar 1-Jun-11 7:35am

Yeah. I've had to edit some questions about 4 to 5 times just to make sure they are removed properly sometimes! -_-!

This application does nothing... getchar() is meant to grab input from stdin, which is the user input by default, yet you don't ask the user for input (I guess you can write it on the screen it in if you knew to do it). Additionally, you try to read the user input until EOF, that doesn't make sense, since stdin not a file, so you'll end up stuck in that infinite loop.

See this example:
