The trouble is that advance does not return an iterator, AND the iterator
(i in your code), has to be double derefrenced because the iterator points to a pointer and hence the error message. You...

I understand for quick solutions you would follow AncientDragon's sage advice.
However, that always leaves a sour taste since I am sure your want to know how to do it:

Ok, for maths courses have a look at the MIT lecture page http://ocw.mit.edu/OcwWeb/Mathematics/index.htm.

This code is a mess, and 99% is that it is mixed c and c++ , it has not been set out tidily so neither I nor you know what is going on.

Things to fix:

Why use malloc to allocate memory use...

Indeed sfou, it is a method that is absolutely instinctive for most programmers. It is mainly mathematicians that have the big hang up with that sort of construct. They (and theoretical physists)...

As far as I understand the standard, this is not possible [I stand to be corrected].

There are slightly upsetting work-arounds.

First: If you don't need the virtual aspect, this is easy use a...

I think that you have got confused with the syntax of declaration and implementation. So here is an example with most of the common things you will likely need. [Please ask if I have missed...

The problem you have is temporary values and what happens to them:
I think this will be clear (I hope :)

The problem is that your are taking a copy of the value in the list. This does indeed...

First things first: Dont use system("Pause") it has been discussed to death here and everywhere on the web.

Second: The next problem is that you are using temp1 without initializing it. i.e every...

You seem to have two cin>>x in your code at lines 23 and 21. I would delete line 23.

I might make count and integer but that is minor.
you have remembered to initialize your variables which is...

Welcome to the real world. There is not free lunch.... sorry.
So

(b) decide that the class is not a good use of time and...

You have forgotten to use the return value of flip(). If you did this

A multitude of errors, mostly caused by trying to write everything in on go.

If you are writing a Pong game, I think that you are going to learn a lot, so well done.

If you don't want to post your code, then maybe a cut down version. But the quickest way to do it yourself is to compile with debug info on and then run and wait till it crashes. The backtrace will...

while you are fixing this. Please note that you often write

This thread is getting a bit messy. So I am going to write a quick summary and how I would tackle the problem.

First: Coordinates are almost never integers, and once you have solved a 2d problem...

Sorry, but most of these solutions are inelegant and that is because to achieve randomness they require an excessive number of random number calls:

You can't copy it to a set and back again without breaking the order.
Sets store on a compiler defined manor but normally red-black trees.
Hence you will destroy the order.

Below I am going to post a working set of code.

The requirements are simple. You write an implimentation of foo and you put template class Foo<float> in that implimentation.
This is 99% portable...

Please note that the code you have is 99% wrong.

Consider

Polynominal A;
A=A;


And before you say you would never do that, be very very careful of compiler opimization, double loops that...

That is no fun comatose!!!! The program should write itself without reference to the source code!!!

You want to look up quine

errh... sorry Ancient Dragon, but the last line of the file is just "="?
Which was what I was trying to allude to.

The probelm seems to me to be that you read that with a statement...

Ok the usual rant: I hate system("PAUSE") and CLS. They are non-portable, and I can clear my own screen if that is what I want!

Beyond that you haven't given us much to go on.
You don't test if...

Returning to the problem asked:

The problem is that you have created a class that does nothing.
If you take the trouble to create a class don't ignore the values.
You can put tar=100000; and it...

Please be VERY CAREFUL with this code.

Consider

// THIS IS VERY VERY WRONG!!!!
char * getName(){
char buf[YOUR_ARRAY_SIZE];
sprintf(buf,name);
return &buf[0];
}

I think that the problem is not the code, but your maths.

Let us start with a number, e.g 89 as use used. What does writing 89 actually mean: that there are 8*10 + 9.

If you write in base 4 ,...

I wish to comment again, since I now have understood what you are doing!!!! -- Well at least the problem, the code that is a different problem.

Let me see you want to get a position were the...

I was the original person who suggested using a sieve of eratosthenes. Now does this still hold? I believe so and here is why.
You were required to find the factors. The only factors of importance...

This is a problem that requires thought NOT code.

The answer can be easily found on a piece of paper.

So without giving you the whole solution try thinking about this
Obviously 20!...

The obvious stuff is wrong : use of '\n' rather than std::endl. the complete lack of tests for input values.

e.g Would this be wrong

IntStack stack(-40);


so that is why you have a problem...

The question should be asked "how do I delete a pointer if I allocate the memory using xxxx?"

Let us review:

Looks like you are coping the pointer BUT not coping the array.

What happens is the memory for array1 is overwritten with something else and you have a copy of...

You haven't looked at the messages at the top of the forum.

And that is equivilent to

num++;


That means that player == 1 or 0, and both of those are...
