Please read the posting guidelines at the top of the forum !!!!!! (it seems that we need to put a lot of exclamation marks in order to communicate).

1/ The posting guidelines are to help YOU get an answer. If you can't be bothered to post politely, why do you expect any replies at all?
2/ This looks a lot like a question you asked within the last few days.
3/ If you read the guidelines, it would tell you about using the pre tag, which preserves indenting, so we can read your code without pain.
4/ You use int j twice. You might get away with it, but if you're struggling to read your own code, then you should make life as easy as possible for yourself.
5/ If you use the debugger, you'll be able to answer your own question. Put a break point on the first line, put all the variables in the watch window.
6/ We can't debug your code for you, as we have no idea what's in your array.
I wish you good luck, and have a good learning experience with your debugger.
Iain.

Well said but I think you're wasting your time. This person has ignored the posting guidelines since 2006 no matter how many times he/she was told to abide by them.

"Ignoring guidelines since 2006" sounds like a motto on the side of a builder's van...
He's now on my ignore list, and it may be time to retire from the C++ board for a few days...
Maybe I could take up C# and become a question on their board/
OMGZ HOW DO POINTER WRK ON IN CHARP?
URGENT!!!!!! PROFESSOR WALKING TO ME!!!!

OK, I'll carry on wielding my blunt knife of wasted sarcasm...
Maybe I'll put "by special request" in my sig.

You chuckled at "Signor Pallini" before - am I wrong? Is the CP for codeproject, and allini means something in Italian?

That's nice idea. BTW, by Special request of CPallini.

Yes, I simply was amused because you used the Italian term (I'm used to have bad times at Soapbox because of my English).

I did check up your profile - the Signor wasn't a lucky guess. You almost had Senor until my brain started firing again.
As for you having bad times about your Inglesi[*] - I've not noticed you making mistakes, and I'm pretty critical. And it's hard enough for me to understand some of the butchered english here. I'm curious as to whether being a second language makes them easier or harder for you to parse.
If they give you grief, ask them to translate their complaint into your language. Or have a ![Beer | [beer]](https://www.codeproject.com/script/Forums/Images/beer.gif) on me.

ps, Check my sig!

hi
i want to display a progress bar in listview control as a subitem.
the progress bar would continously be updated and i shouldnt use any images.
i am using vc++ 2005 and i am not using MFC.
i am using win32 programming.
i know this can be done using custom control but if any one knows more than that please reply (i.e with a smaple code)

Did you search on the codeproject?

yes i did but couldnot find it

Hello,
This might be a basic point in C++ but i need help......
This is the code snippet i've been using:
typedef char* myString;
main()
{
myString i="abcd";
myString j="ABCD";
....
}
I need to copy j to i. But i'm not able to use usual strcpy. I also tried assigning char by char using for loop. ( i[1]=j[1] etc). But it didn't work.
I dont want to use array format for the string, it should be char* only. Also i dont want to directly point i to j(i=j) coz it might result in memory leak.
Plz, suggest some alternative.....

No it won't.
Anyway, for such string manipulations, it is much easier to use the string class from the STL (std::string).

A typedef isn't enough to transform a string literal (as well a char pointer) into a string.

The only way that would work would be to change the declarations to:
char i[] = "abcd";
char j[] = "ABCD"; See here for the difference in why one can be changed and not the other.

You should never loose sight of the code generated by the compiler. In your case the Compiler will include two char arrays into the excecutable, namely "abcd" and "ABCB" The fact that you Tyedefed them as myString has confused you more than the compiler. You cannot copy i to j, because both are in memory reserved for string constants. In other words: Both are in 'read only' memory. I strongly suggest that you get a copyof the excelent book written by Brian Kernighan and Denis Ritchie about the 'C' language (Never mind CPP). And rephrase the question above after reading these books.
If you do the appropriate amount of study,you will realise that in the above example code fragments, memoryleaks are not even close to being an issue.

is there any technical difference between invoking a constructor using
class obj(5,20) and class obj=class(10,40).
Thanks in advance

Not if you don't read the sticky posting called "how to get answers", and the line that says "please use meaningful subjects". I've yet to see someone post a message with a subject of "ignore this - I don't need any assistance".
But I'll be nice anyway..
1/ The numbers are different, so there will be differences.
2/ Less trivially, the first example just calls the constructor. The second example makes two objects, (obj, and a temp one), then copies temp to obj, then destroys the temp object.
If it's CPoint, then it's trivial. If it opens / closes databases, does a network operation etc, then the difference could be HUGE.
Iain,
-------
Update: See CPallini's and my conversation later. Short version: No actual difference between the two bits of code (except the numbers!)
