Hello,

I am trying to understand recursion by using the following example.

   <br />
#include <iostream><br />
#include <iomanip><br />
<br />
using namespace std;<br />
<br />
unsigned long factorial( unsigned long ); // function prototype<br />
//-------------------------------------------------------------------------<br />
int main()<br />
{<br />
   // Loop 4 times. During each iteration, calculate factorial( i ) and display result.<br />
   for ( int i = 0; i <= 4; i++ )<br />
   {<br />
	  cout << "\n i = " << i << endl;<br />
	  cout << endl << setw( 2 ) << i << "! = " << factorial( i ) << endl;<br />
   }<br />
   return 0;  // indicates successful termination<br />
<br />
} // end main<br />
//-------------------------------------------------------------------------<br />
// recursive definition of function factorial<br />
unsigned long factorial( unsigned long number )<br />
{<br />
   // base case<br />
   if ( number <= 1 )  <br />
   {<br />
      return 1;<br />
   }<br />
   // recursive step<br />
   else  <br />
   {<br />
	  cout << endl << "number = " << number << "    factorial(number - 1) = " << factorial(number - 1) <br />
		   << "    number * factorial(number - 1) = " << number * factorial( number - 1 ) << endl;          <br />
      return number * factorial( number - 1 );<br />

I do understand that when i = 0, the base case is true, therefore 1 is returned. 0! = 1

When i = 1, the base case is true and 1 is returned. 1! = 1

When i = 2, the base case is not true, so number * factorial( number - 1 ) is returned, which is 2 * factorial( 1 ). 2 * 1 = 2. 2 is returned. 2! = 2

At this point, I have a question. The next line says i = 3. Then it says number = 2. How does number become 2 if i = 3?

Thanks,
Eric

The recursive calls have to complete before the output can be sent to cout. So what you're seeing is the output from the deepest recursive call first.

Hasn't the output already been sent to cout? The program already output 2! = 2 and i = 3.

At the point in the program where i = 3 is output, doesn't that signify the beginning of a new iteration?

Thanks,
Eric

It appears that you are calling factorial() three times within itself (one for the algorithm itself, and two for the cout statements). With all of those cout statements, that may be leading to the confusion.

If you are trying to track the stages of recursion with the cout line then I suggest that you minimise your confusion by calling your recursive function just ONCE and storing the result to use in your cout line and to return, I think that this will you help dissect what is going on?

Good luck I´m sure it will just click and you will go "Ah!" Smile | :)

OK, thanks to all of the great feedback, I have a better understanding about recursion.

I am now attempting to apply it and I have come across a problem that I can't seem to pinpoint.

I have written the "eight queens" program, but for some reason, I get an infinite loop. I think my base case is ok. Can someone help me figure out what I am doing wrong here?

Thanks in advance,
Eric

WinInet FtpPutFile

Hello everyone,

I'm writing a simple class to handle FTP SEND of a file from a WinCE 4.2 box. I'm having some trouble with the FtpPutFile call. I've tried several FTP servers using a valid username & password and get the same error every time.

InternetOpen succeeds, InternetConnect succeeds, FtpPutFile returns FALSE, GetLastError returns 12018.

The error message 12018 is defined in WinInet.h as follows
#define ERROR_INTERNET_INCORRECT_HANDLE_TYPE 12018
The type of handle supplied is incorrect for this operation.

Any input is greatly appreciated!

Two problems. 1) InternetConnect() return a HINTERNET but you're treating it like it returns a bool. 2) You're passing the wrong handle to FtpPutFile(), you need to pass it the handle returned by InternetConnect().

Hi,
In release mode , the project is searching for MFC42UD.lib file.
Any idea why and where we have to chnge the project settings, because to my knowledge somebody tampered with the settings

Reading file with X/Y axes?

Hello everyone! Big Grin | :-D

Am I reading my file correctly?

        for (int i = 0; i <= HEIGHT/32; i++)<br />
		{<br />
			char * curLine = new char[WIDTH/32];<br />
			f[x]->getline(curLine, WIDTH/32);<br />
<br />
			for (int j = 0; j <= WIDTH/32; j++)<br />
			{<br />
<br />
				// Get character in temp line<br />
				char v = curLine[j];<br />
<br />
				// Exit if EOF was found<br />
				if (!f[x]->good())<br />
					return;<br />
<br />
				if (x == 0)<br />
					fputc(v, outputz);

I noticed that if I open the file in Notepad, the character counter says 16, but if I count the chars with my fingers, I only get 15! Mad | :mad:

I want to get each line, and then write each character in that line to another file, individually. What's the right way of doing it? Much thanks! Wink | ;-)

PS: I've been struggling with this program for more than 1 month... I suck... Confused | :confused:

Update!

I got the main problem away (NULL characters showing up at end of each line)
But now, the last line doesn't get written... Here's the updated code:

        for (int i = 0; i <= HEIGHT/32; i++)<br />
		{<br />
			char * curLine = new char[WIDTH/32];<br />
			f[x]->getline(curLine, WIDTH/32);<br />
<br />
			for (int j = 0; j < WIDTH/32-1; j++)<br />
			{<br />
<br />
				// Get character in temp line<br />
				char v = curLine[j];<br />
<br />
				// Exit if EOF was found<br />
				if (!f[x]->good())<br />
					return;<br />
<br />
				if (x == 0)<br />
					fputc(v, outputz);

Much thanks! Wink | ;-)

hi,

i'm new to c++, still learning it. i am trying to learn some basic registry functions for use in other programs i may make. i have a subkey: currentuser/software/name/program

inside "program" i have a few values (all strings). how can i get the list of all values in the subkey?

i'm looking for the simplest possible way.RegCloseKey(hKey);
thanks in advance,

You can use this function:
Here you have to pass the valueName to access it's value.
Specify the Root key where your subkey is located

CString YourClassName::GetValueFromRegistry(CString regValuName)
{
char lszValue[255];
CString str ;
HKEY hKey;
LONG returnStatus;
DWORD dwType=REG_SZ;
DWORD dwSize=255;
returnStatus = RegOpenKeyEx(HKEY_CURRENT_USER, "currentuser\\software\\name\\program", 0L, KEY_ALL_ACCESS, &hKey);
if (returnStatus == ERROR_SUCCESS)
{
returnStatus = RegQueryValueEx(hKey,regValuName, NULL, &dwType,(LPBYTE)&lszValue, &dwSize);
if(returnStatus == ERROR_SUCCESS)
{
str = (LPCTSTR)lszValue;
}
else
{
str="";
}
}
else
{
str="";
}
RegCloseKey(hKey);

return str;
}

Hi everybody,

I want to include few external DLL files into my executable file as a static Library.

Microsoft Visual C++ can do that with MFC,my question is: How can I do to insert external DLL's files?

I hope any body can help me!

Thanks

DLLs and static libraries are entirely different things. MFC does not do what you said, MFC just has both DLL and static LIB versions.

OK, let the world be more "friendly" to this guy (or gal?)... If you want to do that with say MYDLL.DLL, then you must locate (or steal or beg or borrow or build) the .LIB file MYDLL.LIB. If you have the source code of MYDLL.DLL, then building the LIB file is a piece of cake. After you get the LIB file, link it statically by adding it to the Link tab of Project settings (do not forget to add its path to the Library path list in Tools --> Options --> Directories).

If you do not have (or cannot get) the LIB file, you cannot do it.

Window Handle,Class, FindWindow API

Hi. Can anyone tell me how I can establish the "Class Name" for my application's window?

I want to use the FindWindow API that looks like this: LONG FindWindowA(class, title).

What I want to do for my C++ app, MyCPPApp.exe, is establish the "Class Name" to be something like "JohnsApp".

I have used Spy++ to look at other Class Names,
XLMAIN - MS Excel
OpusApp - Word97
...

I also want to use FindWindowA( ) to send messages between two applications.

Thanks,
Johnny

Ok, so what does it indicate for your application's window?
