Re: Check on correctness

It is the nature of for statements that the first and third clauses have side effects. So
indeed I exclude those from the "no assignments" or, more generally, "no side effects"
rule.

Whenever I find assignments embedded in code I'm working on (and it is never my code), I
just rip them out, and replace them with separate assignment statements.

Hi Joe,

I assume you're excluding for() statements from this rule. For example:

for(int i=0; i < something;++i) {
}

is very common and a proper form of declaration and initialization
especially now that we have decent for scope handling. This keeps the
variable local to the loop and is a consise and coherent way of declaring
nad setting the initial value.

I agree with you on other types of statements. For example:

if(x=1) {
}

would work, but not likely how the programmer intended. Fortunately, we get
a nice fat warning for this one.

Of course, this compiles in either release or debug modes

You need to do two things to become a better developer:

Never, ever under any circumstances embed assignments in any other
construct. Not in an if, not in a while, and most especially not in an
ASSERT.
Embedded assignment is a very poor programming methodology, and serves
little if any useful purpose at any time and should be abandoned as a
programming technique

Never, ever, under any circumstances make any document or view class
visible
to a dialog. Dialogs should only work on their own member variables or
structures used for communication and not know about anything else outsdie
themselves.
