If you want cross-platform then use c++ boost libraries

The first thing you need to do is split up the Hotel class into three different classes

1. GuestInfo
2. RoomInfo
3. Hotel

class Hotel should contain an array or vector of RoomInfo classes

class RoomInfo should contain an array or vector of GuestInfo classes, as well as the room number and other objects related to the room. When you need to change the room number all you have to do is locate the instance of RoomInfo from the array/vector in Hotel that has the same room number as the current room number, then simply change the room number in that RoomInfo instance. Of course when you enter the new room number you need to verify that the new room number isn't already taken.

Incidentally, I thought sizeof would give the size of whatever type was given to it
be that an int pointer or a double type.

It does -- all pointers have the same size.

sizeof(u_char)

You don't need that part because char and uchar are always guaranteed to be 1.

SendInputs()

int raw_len = sizeof(MyTest_u_char2) + 1;

That line is wrong -- sizeof takes the size of a pointer, not the number of bytes allocated to the pointer. In this case sizeof(any pointer) is 4 (in most implementations today but could be some other value depending on your compiler). What you want is the const 8. Better to declare a const int for that and use it throughout so that you don't have to repeat magic numbers all over your program.

can you please write a program for me

Nice of you to ask, but No, we are not here to do your homework for you.

There are several higher-level c++ alternatives, such as C#, Windows Forms (which is CLI/C++), MFC, wxWindows, QT (cross-platform) just to mention a few. C#, WF, and MFC you will want to use Microsoft's VC++ 20?? compiler/IDE.

if you want to copy the arrays that are declared in oneFunction() into the arrays declared in twoFunction() then onefunction() will have to call twofunction() passing it the two arrays. twofunction() will need two parameters, not one.

1. EnumWindows()

2. See my previous post about gdi functions, especially BitBit()

Kind of hard to say what the problem is without knowing the declaration of variables.

Maybe, I just added & in my signature and it's ok.

read this article for keyboard input

They probably need to escapt the \& symbol

[edit]. well, according to the line above & doesn't need to be escaped, so I have no idea what the problem is.

Maybe a map is not the best way to go about that. Another way is to create a structure that contains a string for the argv entry and int for counter, then create a vector of those structures. After that, just call std::sort() to sort any way you want it.

yes it is opossible, how to do it depends on the operating system. For MS-Windows you need to learn win32 api functions. Here is a good tutorial. After you have learned that you can start learning MS-Windows GDI functions

wishes grated. But ...
1. You landed on mars and burned to death
2. you are instantly teleported back 5 billion years long before there people or planets, and no other way to get back home.
3. I stole one for you and now you are in possession of a hot bike, and you get 10 years prison for possession of stolen bike.

line 71 must be int main()

Why is this an issue here ?

India is the only place where I've read that complaint at DaniWeb over the past 8 years. I wasn't trying to make it an "issue", just a passing comment.

If the OP is from India he may not have any other choice but to use Turbo C/C++ because sadly that's what is taught in their universities.

I just googled for it and found this tutorial as the very first hit

If you want to find out if the code works correctly then you have to write driver programs to test all of its features. In main() instantiate an instance of the class then add a few lines of code that call each of the class's methods and print out the results of the calculations. Don't expect other people to do your job for you because it ain't going to happen.

found it.

I just went to my profile and could not find any way to change username or delete membership. I guess its because I have been a member too long. Doesn't matter -- I was just curious and don't intend to do either.

Change user name: how many times can they do that?

What do you want from us?

wprinf() and related functions work with unicode characters. You may have to change the code page in order for other languages to display correctly.

Any idea as to how this question should be done .

Yes -- find out how to use magick++

You need to do socket program to send/receive over the internet. Exactly how it's done is operating system dependent, e.g. MS-Windows see turotials for winsock, for *nix there is POSIX sockets. There is lots of into on the net about both which you can easily find by googling. Hardware isn't much of an issue with sockets, your program could care less that kind of hardware is used, such as wired or wifi or what network adapter.

without to much coding and hardware involved"

There is a lot of programming required in C language. Its a little easier in c++, and I think easier yet with CLI/C++ (a .NET language).

In a way communism was good for the world -- many of the things we have today was because communism gave us the incentive to build bigger and better things. Space exploration, for example, may not have happened had the Soviet Union not started it first. The microchips used in today's computers were a direct result of that action.

tutorial on how to produce a shared library

how to get pid

line 17 should be moved up so that its within the bracketed if statement that starts on line 13.

Attempting to do it a "portable" way is useless becuse *nix doesn't support DLLs, instead it has shared libraries with *.so exension.

Also is there a way I can program for linux on windows?

Only if you run *nix in a virtual machine window and use a compiler for *nix such as gcc and/or g++. Have you looked at any of boost cross-platform libraries to see if there is something you can use?

How can I get a DLL's Parent Window Title?

GetModuleFileName() will return the fully qualified path to the processes that loaded your DLL.

I don't think there is anything else in C or C++. Use a different language, such as C# or CLI/C++ (both .net languages). I think php is used for most server-side programming.

An answer I am looking for is something along the lines

Post a request in DaniWeb Community Feedback

An answer I am looking for is something along the lines

Because that's exactly how its done.

You are going to have to create a new lib project in vc++ then, using the makefile you have from *nix figure out what *.c and/or *.cpp files need to be added to that new project. The task won't be easy because makefiles have a tendency to include other files. I have NOT done this nor do I intend to do it.

Read about cgi programs, a short tutorial is here

Can someone tell me how to write

You already answered your own question.

maybe line 6 should have been this: tmp = new int[nCards+1];

DisplayAll(Players);

lines 59-61: If that is a prototype then it should be DisplayAll(Players&)

From what little I've read about it here you shuld prolbably use Code::Blocks with MinGW, which is the windows port of GCC because png++ is documented to work with gcc and not VC++. That's not to say you can not use vc++, just that the port will be easier with Code::Blocks.

what "issues" and what function? If there are compiler errors then post a few of them.

Read this thread

xcode is for MAC, not MS-Windows.

There are ways to handle that too.

instead of all that shifting I just store it in a char array then xmit the array

inx x = -123;
unsigned char buf[sizeof(int)];
memcpy(buf,&x,sizeof(int);
// now just xmit buf
 Serial.write(buf,sizeof(buf));


 // C++ code to convert the captured bytes back into a long integer
 int x;
 memcpy(&x,buf,sizeof(int));

 // or this works too
 x = *(int *)buf;

Not considered in the above code is endianess
Binary data is not directly transferrable between MS-Windows and *nix because the byte order is different.

how can i link my file to this question?

One of the items in the purple ribbon above the edit box is Files -- click that link.

The first problem is the program is attempting to change data that is stored in read-only memory. String literals can't be changed. You can correct that by storing the string in read-write memory like this:

char data[]="ALOK KUMAR   ASHISH KUMAR   ANKUSH

After that you will want to set pointer t = data.

Most likely because there has already been enough said on that thread. It's all about suggestions -- take it or leave it, that's your choice.

Is the code beginning on line 21 of Intro.h really in intro.h or is that just a posting mistake? It should be in a file named intro.cpp. If you really have it in intro.h then that is a problem, remove it and put it in intro.cpp.

As for the undefined errors, that means the linker can't find the named symbol(s), check for spelling and/or capitalization errors.
