i needed to write a prog to display which line a character is found in, in a text file
so basically my problem is checking for the new line or end of line
i mean
if(ch=='\n')
line++;
doesnt work
someone tells me cr(ascii val = 13) and lf(ascii val = 10)
are the chars to check for
what would be the syntax if i need to check
one char from file as equal to 2 ascii values
can anyone give me the syntax of that one if statement to check for end of line
be a help
Check for the new linefeed character (ASCII 10).
In Windows, you find that text file line ends are marked by a carriage return & linefeed pair. While in Unix/Linux they are marked by just a linefeed.
You may want to read up to linefeed, & then check whether the character before it is a carriage return & perform the necessary action.
you can place eof() in your code and check it that way. I believe its ctrl Z to execute it...at least if your using MV C++.Quote:

I hope this helps you!

Why if(ch=='\n') doesn't work??
isn't it the ASCII code for the newline and line feed?
Yes it does. I think I was confused on what he was asking for. I apologize and Thanks for the clarification, ammar.Quote:

Why not use getline. You'll have to set the max line length, so it won't work too well if the input data is longer than you expect.
It works for me... maybe you should show some code ;)Quote:

thanks guys for ure help
i figured out what the problem was
i was using
fin>>ch;
but that is error prone and was screwing up in this case
aaaahhhh i know
so i used fin.get(ch)
worked fine
if(ch=='\n')
is the right condition for end of line
carriage return(cr) and line feed(lf)
are new line characters when u open the file in binary mode
