Header required for 'TButton' is missing i think.

You probably need a class called 'Player' which has a stack data member of type card. You can use the c++ stack container which provides you methods to add/remove elements. You don't really need to learn linked list to understand how this container works but you should still learn about …

We have a small team of 5 software developers and we are handling products A & B. Last month we were also handed over products C & D from another team which moved to doing something else. Suddenly we have double the work and same number of people. Though we …

Normally you would have an insert function which takes care of head node. Not sure why would you want to insert at tail directly. Also you can have insert_at or insert_after, insert_before functions which also handle adding a node to an empty list. Take a look at this tutorial here …

Please post the compliation errors if you want quick help.

Can you post whatever code you have written so far ?

I have a some libraries which have a lot of common classes but the namespaces are different. Most of the code I was writing could be easily reused by classes in both libraries so after some reading I tried a technique of using the templates to pass namespace. As you …

I didn't really know what 'isalnum' does so i checked the c++ reference site and it says "Check if character is alphanumeric. Checks whether c is either a decimal digit or an uppercase or lowercase letter." So that seems to be the issue ? May be you should use 'isdigit' …

Also when you declare a non-virtual function in a child class which has the same name as the base non-virtual function you end up 'hiding' the base function which might not work as you expect. The base class function is not accessible in the derived object now. Even if the …

Are you learning C++ ? What material are you using ? Any decent C++ book or online resource should give you a good explanation of arrays and how they are used. Try this http://www.cplusplus.com/doc/tutorial/arrays/

Why do you need an automata ? It doesn't look like you need to check for strings matching any regular expressions. Just load the contents of the documents as string and do a find for the required strings.

There is a related article link on this page (i'm assuming you see it too) [File Display Proram](http://www.daniweb.com/software-development/cpp/threads/432845/file-display-progam) , Take a close look at the includes, the use of ifstream object for reading files, namespace std, cout etc.. That is the std c++ way of writing code. i'm guessing you've …

Yes. You are subtracting ascii value of char with ascii value of '0'

I don't know why you are getting this error, I would expect something like 'invalid use of non-static member in static function' error over here. Since getStaticGroupData is a static function of the class and mGroups is a non-static member of the same class and you are not allowed to …

I'm just worried how much data is being held by one particular company. And even though they say that they will not misuse the data, they do realise the kind of power it gives them in this e-society. Tracking people's transactions is going to be another such way to get …

If you are really interested in learning C++ and becoming a good programmer, take all this advice constructively. Tomorrow when you go out to work in the professional world and do these mistakes, no one will point them out to you, they would probably just fire you. So, there's no …

instead of an array you can use 'vector' to save unnecessary allocation of memory.

Hi, Could you elaborate clearly what is it that you want to do and what are the issues you are facing ?

I have been reading the 'inside the c++ object model' by Lippman and one of the sections has me a little confused. It is the section where the author explains how virtual tables are created and virtual pointers assigned, in the scenario of multilevel, single inheritance. If anyone here has …

It looks to be this line [code=c++] for(node *temp=firstNode; temp!=NULL && temp->next!=NULL; temp=temp->next) [/code] Lets say you removed the one and only node in your list. In the code you hit the else part and do a 'delete firstNode', however you are not setting the pointer to null. Then you …

Have been reading about the facebook commenting API for a few days now. Sites like Techcrunch have gone ahead and implemented the feature. I tried imagining if it will make sense for a forum like Daniweb to enable facebook commenting ? To me it seemed that it will not make …

Looking at your printmaze function it looks very likely that you have missed some matching opening and closing braces somewhere. Just try and ensure that.

It seems like you want a subscriber-publisher model. There will be one publisher thread which calls a particular function on all subscribers every 60 seconds.

However if there is only 1 publisher then …
