Unfortunately that happens, and aging doesn't help. Interestingly enough, in spite of 0x01AA remark,
g++doesn't complain aboutclass Foo
{
int F;
public:
Foo(int f){F = F;}
//...But it does complain about (which is, by the way, the construct every sensible
C++developer would have chosen)class Foo
{
int F;
public:
Foo(int f):F(F){}
//...spitting out a sane
warning: ‘Foo::F’ is initialized with itself

I don't even know what language this is, but I will presume Java. :^) You have Value3 being assigned to the value of ... Value3, so nothing happens there. Evidently, it is initialized to the value of 0. Is it a default int when there is no declaration type? :confused:

C#, and exactly. Stared and stared and stared and debugged and stared and had another coffee then... :doh: C# will warn you if you do "=" instead of "==" but I was surprised it didn't warn about X = X.

I saw it fairly quickly, there again this sort of case is very easy to miss when you are the one who wrote it. It's the reason why rubber ducks or cardboard programmers are so important.

Because your code is doing what you told it to do - not what you want it to do? (That is usually my problem with my code!)

I'm surprised there were no compiler errors.
It is always interesting to me that C# doesn't produce a compiler error for that. But, I guess it figures you know best. :rolleyes: Maybe there's a warning, but we all ignore warnings. :laugh:
I have had a number of cases where Visual Studio suggests that I should make a variable readonly, for reasons somewhat similar to this one (and I have had similar problems spotting it). That is when there is only a single assignment to the one variant of the name - it is not smart enough to detect that I have declared two differently named variables for the same "real world" value, using one name in half of the statements, the ohter one in the other half. I wish it was that smart :-) (I can think of only one time this happened, though.)

There is no warning, which surprised me - and I have "treat warnings as errors" set by default ...

It often issues warnings when there is also an error. Otherwise you're on your own... We're philosophical about power outages here. A.C. come, A.C. go.

Because it's emulating the English language: I am I You are you He is he... or maybe she... or he could be it! Warning, Will Robinson! In English, this would be picked up earlier -- at the editor level, not compiler.

Given that I just passed my 28th anniversary in my current position, I have had 3rd and even 4th-generation opportunities for self-slappage. I keep waiting for one of my past selves to show up and say "Look, you senile old git! We did this before, this was the wrong way, you had to fix it, now get it right the first time!"
