testing for the newline

[bacadman]

I have a variable that seems to be placing a newline when outputting to
a file. How can I test to see if this is the case.

Show us the code you're using, perhaps then someone can tell you what's
going wrong. A variable as such never outputs anything. It's probably
your call of printf() (or whatever you're using to print the variables
value).

if(line[strlen(line) - 1] == '\n')
line[strlen(line) - 1] = '\0';

if(line[strlen(line) - 1] == '\n')
line[strlen(line) - 1] = '\0';

Which is a good way to kill off the trailing newline in a string.

But, the OP didn't make it clear that this is what is happening. It could be
that the newline is a single character (as in printf("%c",'\n'); ), or even
imbedded at some point inside a string (as in printf("%s","abc\n123"); ).

Neither of these cases are addressed by your (good) code fragment.

if(line && *line)

if(line[strlen(line) - 1] == '\n')
line[strlen(line) - 1] = '\0';

We don't want to look at memory outside
the string!
