read a line from textfile

[friendjin]

How can I read every line from the existed file.
eg.
the content of textfile:
serialnumber = " 50";
serialfile path = "C:\\doc\\" ;
errorfile path = "C:\\doc\\d \\";

I want to read "50" from the first line to SeNo, read ""C:\\doc\\ "from the second line to SePath, read "C:\\doc\\d \\" ifrom the third line to ErPath.

any idea how it can be achieved. thanks

open file

Loop untill EOF
begin
read line
search in the line for '='
Now copy the remaining string in to Destination.
end

close file

And if you need help on the functions that go with kvbreddy's algorithm, I find this site to be very good with examples (I also like how they have the other functions in the library of the function (still with me?) you are looking up, off to the left of the screen).

Hi kvbreddy;
Thanks. the problem is I could not workout readline command, and how can I do a search.
I would so appreciate if you could write this part of code for me.

Sorry, but we can't do that. This is in C, right? What error messages did you get when you tried readline?

Sorry about that I did not mention it. it is in VC++.
error is identifier was not found.

Can you post the segment where you use readline() in your code?

Is this written in C#? C and C# have readline functions - I don't believe C++ does... (Please anyone correct me if I'm wrong.)

I actually have already worked out, but I chose another method by using strstr.

but I do want to konw how readline works in C++.

any ideas..thanks

That was what was confusing me. To my knowledge, readline is not in C++. (Though I could be wrong - its happened several times recently)

I personally prefer getline.
