Is this a multi-line edit control? In any case, after the variable is populated with the control's contents, simply call iswhite() for each character.

You can use the CString member function ::TrimLeft() and ::TrimRight() to remove any unwanted characters at either end of your string.

If your string has a mixture of these characters, then its a bit more difficult to infer where your 'valid' input string starts and ends.

Ok..So I'm making a program for the "Connect Four" game. You know the one that you try to get 4 colors in a row by dropping a chip in between 2 players.

Well My problem is my function called displayBoard this method places 2 different kinds of markers on the board (one for each player) and displays some kind of marker for empty slots. Be sure your choices are easy to see.(i.e. X's for player 1, O's for players 2)

Well having the data members being...

//data members
int board[12][13];
int numChips[7];

how would I write the function...displayBoard?

All I have so far is this in my .cpp file

void ConnectFour::displayBoard()
{
for(int i=0; i < 12; i++)
{
for(int j=0; j<13; j++)
{
cout << board[i][j] <<" ";
}
cout << endl;
}
}

The displayBoard() method is fine. What you need to do is populate the board variable with Xs and Os.

You need a method that asks the user which of the seven slots they want to insert a piece into. If that slot is not full, add a piece to it (this is the real meat of your program). Otherwise, tell them the slot is full and ask again.

ok...but all i have is

cout << "What column do you want to drop a chip in?;
cin >> //do i use an arrary for cin?

for(int j=0; j<13; j++)
{
cout << board[j] << "X";
}

Based on this this picture, you should have a 6-row by 7-column board. That said, you could have something like:

int nColumn;
cout << "What column do you want to drop a chip in (1-7)? ";
cin >> nColumn;
 
for (int nRow = 0; nRow < 6; nRow++)
{
    // if the cell is empty, fill it
    if (' ' == board[][])
    {
        board[][] = 'X';
        break;
    }
}

I'll leave the two [][] for you to conquer.

hi!

i've just finished writing a linked list template class, which compiles fine, but when i try to use it in another file (main.cpp) in my console test app' i get LNK2019 errors for every method of the class being used. i've copied the class & output below, so if anyone has any ideas i would REALLY appreciate some help because i'm completely stuck!! thanks!!

void listfunc()
{

string sData2("NUMERO DOS!");
string sData3("NUMERO TRES!");
string sData4("NUMERO QUATRO!");
string sData5("NUMERO CINQO!");

// element 1

pStrElmt = new ListElement<string>;

pStrElmt->SetData(&sData1);

pStrList->InsertNext(NULL, pStrElmt->GetData());

// element 2

pStrElmt = new ListElement<string>;

pStrElmt->SetData(&sData2);

pStrList->InsertNext(pStrList->GetTail(), pStrElmt->GetData());

// etc...

as you can see i've #include'd where needed, & it's compiled fine, but the linker doesn't like it.

i'm pretty sure i did.

i'm using vs.net 2003, & added all files to the project by doing:

'project->add new item' (or it's equivalent)

there's a beginners template tutorial (part 1) on this site submitted by a chap called stefan spenz which i copied into my project in the usual way i.e. class definition into header & class implementation into source file (.cpp), then i tried to build the project with the class being used in main.cpp (with #include "stack.h" for new class where needed) and i had the same problem.

i'm obviously missing something about templates!?

There is your problem. You should include the template implementation in the header file. Read this[^] faq about C++ templates and you should do fine...

Multiply it by infinity and take it beyond eternity and you'll still have no idea about what I'm talking about.

Example:

What does the hpp mean? Is it just for the human eye? Is it any different to the compiler than a .h file?

thanks

David Crow15-Sep-04 2:50

Re: What does *.hpp mean?

15-Sep-04 2:50

It's the name of a header file for a corresponding .cpp file. With C, you have .c and .h files. With C++, you have .cpp and .hpp files. In the past 15 years, I've never used a .hpp file.

The compiler does not care. SOME (but not all) editors switch to C++ mode when the see *.hpp.

I've got an About CDialog that has 2 buttons on it (OK, Release Notes). When I click the 'X' to close the dialog it acts as though I clicked on the Release Notes button. Confused | :confused:

I can close the dialog by clicking OK, any ideas on getting it to close on 'X'?
