Hi
New to C++ but a bit stuck with this one.
I need to print a character eg: "x" multiple times on a console application.
I need to print "XXXXX" on the console in the place of an actual word as the user has to guess what the real word is. (Hangman based game)
i have used "example.length()" to obtain the amount of letters in the word but i need to transfer the "example.length()" to the relevant amount of "x's" to make up the word.
eg:
STARWARS must become XXXXXXXX on the console.
Can anyone help out with this one.
Thanks in advance.
I really hate this darn machine;
I wish that they would sell it.
It won't do what I want it to,
but only what I tell it.

for(int i=0;i<example.length();++i)
{
cout="" <<="" "x";
}
although,="" i="" think="" there's="" actually="" another="" way="" to="" do="" it,="" that's="" the="" most="" straightforward.

The below code is not the simplest way of doing what you want. However, I assume you will be changing the X's as the user guesses the word. Thus, you can modify the PrintChar class to compare the guess with the answer, and print either an 'X' or the correct character.
#include <string>
#include <iostream>
#include <algorithm>
using std::wcout;
using std::endl;
using std::for_each;
using std::wstring;
class PrintChar {
public:
void operator() (const wchar_t& c)
{
wcout << L'X';
}
};
int _tmain(int argc, _TCHAR* argv[])
{
wstring answer = L"telephone";
for_each(answer.begin(), answer.end(), PrintChar());
wcout << endl;
return 0;
}

Thanks George
You have just answered my question and the next problem I was facing as well.
Will work on your code now and try to understand it before trying to implement it.
Much appreciated !!!

This might make more sense to you:
#include <string>
#include <iostream>
using std::wcout;
using std::endl;
using std::wstring;
typedef wstring::iterator wciter;
int _tmain(int argc, _TCHAR* argv[])
{
wstring answer = L"telephone";
wstring guess = L"pXlXXXXnX";
// Make sure both strings are the same size.
if (answer.size() == guess.size()) {
wciter a = answer.begin();
wciter g = guess.begin();
while (a != answer.end() && g != guess.end()) {
if (*a == *g) {
wcout << *a;
}
else {
wcout << L"X";
}
++a;
++g;
}
}
wcout << endl;
return 0;
}

Help me, I need to create a CFormView class with CToolBar, but when update my CFormView, the toolbar disappears. I'm use a MainFrame with CSplittstWnd, so the my program use many CFormView as controls. Inside de CFormView, I call the CtoolBar in OnInitialUpdate;
What is the error?
part of source code:
void CForm2::OnInitialUpdate()
{
CFormView::OnInitialUpdate();
// TODO: Add your specialized code here and/or call the base class
if (!m_toolBar2.Create( this ) ||
!m_toolBar2.LoadToolBar(IDR_TOOLBAR2))
{
TRACE0("Failed to create toolbar2\n");
return; // fail to create
}
m_toolBar2.SetBarStyle(CBRS_ALIGN_ANY | CBRS_TOOLTIPS | CBRS_FLYBY);
WINDOWPLACEMENT wndPlmnt2;
m_ctrlTB1Holder2.GetWindowPlacement(&wndPlmnt2);
m_toolBar2.GetToolBarCtrl().SetWindowPlacement(&wndPlmnt2);
m_toolTip2.Create(this, TTS_ALWAYSTIP);
CRect rect;
m_toolBar2.GetToolBarCtrl().GetItemRect(0, rect);
m_toolTip2.AddTool(&m_toolBar2, ID_TB2_ONE, rect, ID_TB2_ONE);
m_toolBar2.GetToolBarCtrl().GetItemRect(1, rect);
m_toolTip2.AddTool(&m_toolBar2, ID_TB2_TWO, rect, ID_TB2_TWO);
m_toolBar2.GetToolBarCtrl().SetToolTips(&m_toolTip2);
GetParentFrame()->RecalcLayout();
ResizeParentToFit();
}
//////////////
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
(...)
if (!m_wndSplitter3.CreateView(0,0,RUNTIME_CLASS(CForm2),CSize(cr.Width()-100,cr.Height()-100),pContext))
{
TRACE(_T("failed to create view in third pane"));
return FALSE;
}
(...)
Later, I do another call the other "CForm1", but I return to "CForm2", your toolbar disappers, undertand?

Hi All,
I'm writing a program, part of which needs to read text from a .log file in UNICODE line by line, then convert it to ASCII and write it to an ASCII .log file line by line...
I've been battling with this issue for a week, and have yet to find a solution.
PS: I'm writing in C
Thanks a lot
Alex

Where can I post my Java questions?
Java kinda resembles C++, so can I post it here?
Thanks.

You can, but you won't get very many responses ... and quite likely will get yelled at for doing so.

I'm trying to use a string as a parameter for CreateWindowEx and I'm getting compile errors. Firstly I was just casting it to a LPCWSTR as this was what the compiler error message was reported. This wasn't working as I was also casting from Ascii to UNICODE. _T() sorted that out. But I can't get _T() to work when I'm using a std::string. When I try and compile this code:
HWND hWnd = CreateWindow( _T("Barry's D3D BaseClass"), _T(windowName),
WS_OVERLAPPEDWINDOW, 100, 100, 300, 300,GetDesktopWindow(),
NULL, windowClass.hInstance, NULL );
gives the following error:
c:\documents and settings\barryod\my documents\visual studio 2005\projects\directx1\directx1\directxbase.cpp(38) : error C2065: 'LwindowName' : undeclared identifier
I'm not sure why its generating the LwindowName identifier, I've tried the .c_str function but that doesn't work either. Any help would be really appreciated.

If you are trying to write code (using the STL string) that will be compilible on both ANSI and UNICODE builds, you need to do a little work:
#ifdef UNICODE
typedef wstring tstring;
#else
typedef string tstring;
#endif
There are a few other classes you may want to do the same thing for. Basically, what you will want is to use wstring when building with UNICODE, and string when building ANSI.

Thanks for the reply, I've added the above #ifdef to the header file of the class I'm trying to call this method in and in the .cpp file as well but neither seemed to have an affect. _T(windowName) still throws the LwindowName undeclared identifier and windowName used directly as a parameter throws this:
c:\documents and settings\barryod\my documents\visual studio 2005\projects\directx1\directx1\directxbase.cpp(49) : error C2664: 'CreateWindowExW' : cannot convert parameter 3 from 'std::string' to 'LPCWSTR'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
Am I doing something wrong or is there anything else I have to do?

Assuming windowName is the name of your tstring variable, you don't need the _T() macro. Just call it using windowName.c_str().

Hello All,
A few quick questions that i would really appreciate some answers on:
The standard template library vector (i.e. vector<myobjec> myVector) - can you double subscript it (i.e. myVector[2][3])?
Do vectors (again from the STL) inherently allocate dynamic memory (the more abundant kind)? In other words, if I use the pushback() method, is the vector allocating that memory dynamically on the heap (or free-store)?
Thanks, any help or advice would be great.
Have a great day.
Peace,
BP

Yes, when required but normally not for every push_back()
