Why should it qualify as a horror? Admittedly, the use of strings in that fashion is not terribly efficient, but since they're small and the number of operations is comparatively modest I wouldn't consider the inefficiency particularly objectionable if the code isn't executed too often (if 90% of the time is spent in 10% of the code, it wouldn't matter much if the other 90% of the code were twice as slow as it should be).
My own preference, especially if more parts were being assembled into the string, would be to either use something like a StringBuilder so as to avoid repeated allocations for the different partially-assembled strings, but I don't see anything particularly wrong with the code as given, or else (if using C++ or C#, as opposed to VB) spread one statement over multiple lines. The strings in the above example are short enough that using a simple string type is probably fine, though, and spreading statements over multiple lines isn't particularly aesthetically pleasing.

I need to read a file from the bottom is it possible in c language ?
The exact requirement is
suppose having a file like
========================================
hi
how are you
exit 1
then
you
exit 1
and i can
make this
exit 0
===========================================
I need to read the file from bottom to search the last exit 1
and print the lines above it
the output will be
then
you
Can anybody help me ??

Yep that's a coding horror.
And by the way of course you can do that in C - try poking around in stdio.h and reading a book or two. Maybe use Google.
I am convinced that lobotomising users will make little to no difference.

I still remember having to write your own code in FORTRAN rather than be a cut and paste merchant being pampered by colour coded Intellisense - ahh proper programming - those were the days

No, you have it wrong. He said he needed to read the file from the bottom:

Mostly, when you see programmers, they aren't doing anything. One of the attractive things about programmers is that you cannot tell whether or not they are working simply by looking at them. Very often they're sitting there seemingly drinking coffee and gossiping, or just staring into space. What the programmer is trying to do is get a handle on all the individual and unrelated ideas that are scampering around in his head. (Charles M Strauss)

Standard header files should be included withh < and >.
eg. #include <stdio.h>.

Doesnt that just change the search scope for the file included? which will have little effect if it is increased scope maybe u wil lose 0.00000000001n.S in compile time. (realising that 85% of stats are made up on the spot)
if it does have some esoteric effect that i have been lucky enough to avoid thus far please educate me.

First off, it's good style. Secondly it effects the search paths used.

At the risk of sounding stupid, why don't you do it two phases:
1. Read the file into a datatable, adding an additional column to represent a line number
2. Sort the table by line number (desc) and loop through.

Just read the file into an array of lines, and loop backwards to the first occurrence of the delimiter (exit 1), keep track of the index you found and go from there.

//initialize streamreader
StreamReader myStream = new StreamReader(@"c:\myfile.txt");
//read all the contents and store in string
string WholeFileString=myStream.ReadToEnd();
//convert to array
char []strArray = WholeFileString.ToCharArray();
//reverse the array
Array.Reverse(strArray);
//again convert to string
string newStr = new string(strArray);
//specify the split array (Note \r\n must be specified reverse becoz
string is reverse
char [] split = new char[2];
split[0] = '\n';
split[1] = '\r';
//receive the string array after spliting
string [] Lines = newStr.Split(split);
lines[0] = ; //last line of the file
lines[lines.Length-1] = ; //first line of the file

A programmer told me he just learned try...catch, and found it's very powerful. Later, he found one of his methods always return null after he implemented try...catch. Here is his code:
private DataSet GetData()
{
DataSet ds = null;
try
{
ds = new DataSet();
}
catch
{
}
finally
{
ds = null;
}
return ds;
}

That said, I suggest you and your cow-orker might want to start by learning what the finally block does.
