Re: printf giving extra characters

I am using "printf" with some "\r\n" and it's giving me an extra
character.
Is '\r' the extra character or are you getting garbage characters?
If I use "\n" then I get the effect of "\r\n" but that's
just not helpful.
What is the "effect of "\r\n" "? Garbage characters?
I'm reading a text file and using the contents as
partial output with limited manipulation. The orig file has "\r\n" and
that gives me extra characters when I use printf. The same response is
had from puts and cout.
Is there a #define that I am missing that is attempting to do some
sort of conversion from "\n" to "\r\n" ????
Any string you send to printf must be null-terminated. Neither \n nor \r\n
are null termination. If you are just copying excerpts from your text file
into a char array, then those excerpts will not be null-terminated unless
you manually add a '\0' to the end of the characters.
int main()
{
char test1[]={'a','b','c','\r','\n'}; // not null-terminated
char test2[]={'d','e','f','\r','\n','\0'};// null-terminated
printf("%s", test1); // garbage characters
printf("\n\n");
printf("%s", test2); // no garbage characters
return 0;
}
If that is not the problem, then you need to be much clearer on what the
problem is, preferably with code that compiles and illustrates the problem.
