I use VC++ 2008 Pro. It compiled, but it threw a warning about the use of wcscpy(). The error recommended the use of wcscpy_s() for security reasons. [QUOTE=VC++ 2008 Compiler]cpp22210.cpp(14) : warning C4996: 'wcscpy': This function or variable may be unsafe. Consider using wcscpy_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. …

They are roughly equivalent statements. You can do it with the standard data types too. [code] //both these statements are valid: int myInt(15); //constructor version int myInt = 15; //assignment version [/code] For the standard datatypes, there really isn't any performance penalty for doing it via the assignment version. When …

Your prototype/declaration on line 6 does not match the definition. They must match exactly in order for the compiler to understand what you are doing. The & and * are pointer operators. If you are just learning about functions, you probably haven't learned about them yet. I'm not too sure …

I'm not familiar with the Windows API, but this should say it all: [QUOTE] a BSTR is just a typedef of a wchar_t* [/QUOTE] It is a pointer. Pointers can be NULL. NULL is equivalent to 0, which is interpreted as false by a conditional statement.

Apparently not. The function main() must always be specified "[B]int[/B] main()". If your tutorial doesn't show you that, [URL="http://www.cplusplus.com/doc/tutorial/"]get a new tutorial[/URL] because you're in for a long tedious ride. [edit=someone beat me to it] [QUOTE=photoyid;1142132]Try typing in: [CODE]int main() [/CODE] instead of main(). Also most people write that code …

Good luck with that one. This is not a library archive, it's a discussion board. I'm sure you can find a library somewhere out there.

Line 47, you are attempting to pass " [B]'[/B]red[B]'[/B] " to polygon::setc(). The single quotes cause literals to be interpreted as characters. To make the compiler interpret it as a string, you need to use double quotes. i.e. " [B]"[/B]red[B]"[/B] "

It's not looping because you haven't written any loops. [URL="http://www.cplusplus.com/doc/tutorial/control/"]Read this.[/URL]

The second version is better. You've reduced the ambiguity and you haven't hidden any variables. In addition, the functions are using the member variables to produce results. However..., your function2 is specified to return a double and you have no return statement. This would be a better implementation: [CODE]double function2( …

Read your compiler's error message, it should tell you the line (within a line or 2) and what you did. You're not going to get much help here unless you share the error message.

He's not upset, believe me. He's a mod, he's enforcing the forum rules. We can't help if you just say "I'm getting lots of errors", it's simply not possible without a starting point. You need to tell us what the errors are. Have you done a Site Search? Have you …

You're attempting to re-declare the parameters that you have already sent to the function. The line is completely redundant and not necessary.

Hmmm.... [URL="http://www.daniweb.com/forums/announcement8-3.html"]Read this[/URL] then try again.

Arrays are already passed by reference by default. There is nothing you need to do to accomplish this. An array is nothing more than a pointer to the address of the first element in the array. When you access an element, you offset from the address of the first element …

Is all of your code contained in one file or spread out over multiple files? Based on you mentioning "modules" in your code, and the includes you've listed. I suspect that it is spread out. Assuming that's correct, it's likely that you're not including <iostream> in one of your implementation …

To answer your primary question, you'll need 3 files: 1.) The provided header file (a *.h file) 2.) The class implementation file (a *.cpp) file. 3.) The main application file (another *.cpp) file. The structure of the program will be the same as any other you should have done to …

What's the error? No one can help if they don't know what the error is or where to start...

You might consider making your derived class completely independent of the base class. If you have sufficient control of the source, you could then redesign your derived class to add a pointer to a pre-existing instance of the base object. This would imply a private pointer variable with some sort …

This is the way I understand it: A reference variable such as "p" becomes equivalent to, or a synonym for, "a" and you can use the variable names interchangeably without any special operations (although it's not really recommended for maintainability reasons). If you change "p" you change "a" and vice …

When defining functions, you need to be sure that the prototype's and definition's arguments match exactly. By not making sure they match, you unintentionally overloaded num() and results() to num(long) and results(int, float, double) ... sort of..... Which confuses the compiler.

erm..... none of us are clairvoyants... Would you like to share your code?

Yes, but you'll have to overload the relational operators first. This is necessary so that they know how to compare elements of your class. Otherwise you will probably not get desirable results.

You could test your program on a Virtual Machine. If it messes something, you should be able to just start up a new machine image. My IT consultant does it all the time. Don't ask me how.

You should figure out how to use [B][noparse][code=syntax]...code tags...[/code][/noparse][/B] so that people can read your code.

Do a site search. The answer is easy to find if you do.

A couple suggestions (hint: they're all interrelated): 1. Add a bool variable (perhaps called "quit"). 2. Convert menu() to return something other than void 3. Add a switch case 4. Figure out how to keep calling menu() as long as the user wants to Those should start you in the …

For starters, if you ask me, this looks like a poorly thought out throw together simply for posting purposes. I think you need to pay closer attention to what you are trying to accomplish. I would advise you to sit down with a pencil and paper and do some more …

A much better post, too bad it's not in your other thread... Anyway... You would have to use [URL="http://www.cplusplus.com/reference/clibrary/cstring/strlen/"]the strlen function[/URL] to get the string lengths. Based on what I see, you should be able to get the rest.

You better double check your assignment. Either that or you you need to clarify your situation. What is the purpose of this program? It would wind up insanely large for the intended result... After that, [URL="http://www.daniweb.com/forums/announcement8-2.html"]read this[/URL].

The issue is with your header files themselves, not the forward declaration(s). Your classes are getting defined multiple times, they only need to be defined once.

I can see 2 things. I'm only going to discuss the first, if you correct it properly, the second issue should disappear.

When you define an overloaded constructor (such as a copy constructor), the compiler no longer provides a default constructor. You will have to explicitly define a PUBLIC default constructor.
