right. but that has nothing to do with the code i posted above. this isn't about return values.
in C++ you can do this:
CPoint(5,15);
that will construct a CPoint object and immediately destruct it because the variable is anonymous, it has no name, and it isn't used anywhere.
you can also do this:
MyFunc(CPoint(5,15));
this will create a CPoint and pass it to MyFunc.
the latter case us useful - and it's very common to do this when you need to re-package some data that you already into the types that the function expects.
but the former case is much less useful. if the c'tor and d'tor have side-effects, you could possibly use that to take advantage of those side-effects. but it's very non-intuitive. you would be better off moving those side effects to a function that you could call explicitly.

this will create a CPoint and pass it to MyFunc.
A constructor is essentially a function call. The function returns a value, which may be used like any other rvalue. The expression "somevariable = CPoint(5,15)" has a value which would typically be ignored, but could be used as part of a larger expression. The compiler doesn't particularly care whether or not it makes sense for the result of a particular expression to be ignored; while one typically ignore the value of an assignment expression, and would not typically ignore the value of a constructor, there are situations where one might very reasonably want to do the opposite of the usual case. One may, for example, wish to follow a 'next' pointer and check whether it points anywhere, or force the early creation of a singleton object one is not immediately interested in using.

i'm not sure why you refuse to acknowledge my point.

i'm not complaining about what the compiler does. i'm complaining about the fact that the language allows such a thing to happen.
it makes no sense at all to construct an anonymous object outside of the context of a function call.
this makes sense:
CString t1 = CString ("sdfs");
this also makes sense:
MyFunc(CString ("sdfs"));
this makes no sense:
CString ("sdfs");

Or, "How not to do your release notes.":
str3 = str3 + "<tr><td align='center'><b> Version 2.1.101 • 15 Sep 2007 </b></td></tr>" +
"<tr><td> </td></tr>" +
"<tr><td> </td>• Resolved script error on Reports Viewed List Report</tr>" +
"<tr><td> </td>• Resolved error when adding level using MSSQL</tr>" +
... [snip]
"<tr><td> Corrected Directory Listing query to display Extension Number of Parent Extension </td></tr>" +
"<tr><td> </td></tr>";730 lines have been removed from the string literal to protect everyone, not just the innocent.

Wow... just wow.
As me and my brother debate about regularly, at what point would a 'normal' person stop, take a step back, and say "really... wtf am i doing?". And what should we do with the non-normal people that either keep going for a REEEEEAAAALLLLYY long time, or worse yet, never hit that mark?
From both our experience, it would appear to be - make them CTO.

So not only did he use over 700 unnecessary string concatenations, but he couldn't even put the text INSIDE the table cells?
I must say I'm impressed... It takes real talent to make a coding horror that spans two languages! (Three, if you count English -- Extension Number of Parent Extension? Is that from the Department of Redundancy Department?)

That's highly inefficient too. This is much more efficient:
str3 = "<tr><td align='center'><b> Version 2.1.101 • 15 Sep 2007 </b></td></tr>"
"<tr><td> </td></tr>"
...
"<tr><td> </td></tr>";
That way, the compiler will be able to do the string joins at compile time, rather than at runtime using the overloaded + operator. I'm assuming this is C++ and not C#. The initial str + would not have been needed in C#...

Whoa.. It didn't even optimize the literals when it was compiled? Did someone forget to turn on the optimizer?

Holy Cow Im suprised the debugger didnt have a stack overflow when it saw this!

That looks strangely familiar, did you delete 4 long case statements and about 10 foreach enumerator loops?

OK, what did you replace it with?

CTRL+A, DELETE. Then start it afresh. That would be a safer start than a buggy restart into the crazy maze.

Probably nothing. I'm assuming he's doing maintenance code of something he didn't write (he wouldn't be posting here if he had!). Since it's maintenance, most people are reluctant to rewrite code. Especially if the code looks like this. God knows how the rest of the code looks like...

I did eventually decide to move the body of each loop into its own function. Still uglier than I'd like it to be, but yes, I was reluctant to rewrite it, especially when the problem I was trying to fix turned out to be somewhere else.

One quick guess. Was the project manager had a condition of payment on number of lines code?

Wow! That literally hurt my eyes. 
Unfortunately I have seen similar code for text processing. You have to keep scrolling back up a hundred lines or so to find out where the value stored in that variable came from and just what the heck it is supposed to be; of course it was probably modified on the way down – loads of fun.
