What is a newline?

raptorsoft2000 · 08-04-2003, 09:33 PM

I have been using linux now for 2 months, but i just started in C. When compiling with GCC, i get this error:

"warning: no newline at end of file"

this is probably an easy answer, but i would appreciate any help.

thanks

I looked at that page, and it tells why i need a newline, but i still dont know, "what is a newline?"

what would i have to do just to fix the stupid thing?

thanks!

Move the cursor down to the right of the last character of the last line of text and press the enter key.

Save file and compile.

Newline = new line, as simple as that. it means that theres no new line after the last line of your code. Your application expects to find a new line after every line and when it doesnt it issues a warning.

In other words
An End Of Line character in linux is the 0x0A. The end of file marker is CTRL-Z character. NO newline at end of file means there isn't a EOL character between the last character of text and the end of file marker.

Everytime you press the Enter key a 0x0A character is placed in the file. This tells the editor to move the cursor to the beginning of the next line.
