Take a look at _ltoa[^] function. It will convert a number into a string and you can specify the base of the value (2 in your case).

Iam very happy .. Thanx alot for your helping
let's see the code .. if you have any guestion I will help you
#include <iostream.h><br />
#include <conio.h><br />
<br />
void convert(int i) {<br />
if(i > 0) {<br />
convert(i/2);<br />
cout << i %2;<br />
}<br />
}<br />
int main() {<br />
int a;<br />
cout<< "Please Enter The Number That You Want To Convert >> \t";<br />
cin >> a;<br />
convert(a);<br />
getch();<br />
return 0;<br />
}

Ouch, sorry, I forgot that you wanted to do with recursion (is it a homework BTW ?)
Yup, I think this will work (didn't check it in detail but it looks correct).

I got
remoteAccess error LNK2019: unresolved external symbol __imp__AlphaBlend@44 referenced in function _WinMain@16
when I use AlphaBlend api, I included windows.h in my source code and I can use other windows api without any problem ( I can use BitBlt too which I assume it located in the same dll as AlphaBlend, gdi32.dll)

Please help me somebody..im not good in programming..
i really need someone help to guide me please  i need to design an abstract data structure to represent matrices then i have to overload the *, + and - operator so that they perform the correct operation accordingly for matrices. My friends said that i have to use the two dimensional arrays but then i still can figure out  i have to implement a two dimensional dynamic array to represent the matrix. This is the following code that shows me on how to define a two dimensional
dynamic array of any size (in the example below the size is 2 by 2):
int **matrix;
int rows = 2;
int cols = 2;
matrix = new int *[rows];
for(int i=0; i

Check out matrix TCL Lite[^].
It is a relatively simple matrix implementation. There are more complicated better performing libraries out there, but they aren't easy to learn from.
Using the GridView is like trying to explain to someone else how to move a third person's hands in order to tie your shoelaces for you.

Try this: The Matrix and Quaternion FAQ[^]
Although you can start with a library, you might be better off starting here, learning how and why they both work, and what they can-be/are used for. Plus it is excellent reading on the quaternions too (I use quaternions as often as possible myself). Once you understand how and why they work, and what purposes to use them for, then you can pick your favorite matrix library/class and go from there.

USING Visual C++ .Net
I want to design a class to represent a day’s bookings in an appointment book.
This class should hold the day’s date and an array to represent each hour of
the day for which an appointment can be made (say nine entries, representing 9.00 to 17.00 ).
Each element of the array only needs to be able to indicate whether that hour is booked or not.
the above class should include the following methods:
- prompt for and accept the day’s date
- initialise all the hours in the day to “free”
- repeatedly prompt the user for an hour number
- if the hour is “free” mark it as “booked”
- otherwise tell the user “already booked”
- display the day and its appointments
e.g.
20/12/05
9 booked
10
11 booked
12 booked
13 booked
14
15
16 booked
17
thanks in advance.

it least give him an idea or two to start with
|
|
|
|
|
1) prompt for and accept the day’s date
cout<<"Enter date";
cin>>date; (but before this u need to create a variable for date - i guess u already know that)
2) - initialise all the hours in the day to “free”
u can use a for loop for this.
and yes for 'hour' integer variable u need to create an int array.
3)- repeatedly prompt the user for an hour number
i don't understand.....repeatedly means what intervals it should follow?
4) - if the hour is “free” mark it as “booked”
use the if else construct for this
5)- otherwise tell the user “already booked”
same if then used as in 4)
6)- display the day and its appointments
in a for loop u need to use cout.
I hope that helps u?
Regards

Friends ! I need help !
I have to write a programme in C++ which can listen or sniff the serial port, but without opening the port. The sniffer and the programme which communicates through the serial port has to be on the same PC, I have to write a program which can read ( or listen ) the data that goes out and comes in from the serial port, BUT NOT TO OPEN THE PORT, to let communication programmes communicate through serial ports.
If anyone has an idea how to write this sniffer programme, please send me a advise.
Many thanks !

Don't cross-post. Your question is C++ related so it has to stay on the Visual C++ forum, it doesn't belong to this forum (which is for managed).
|
|
|
|
|
Why do they have to be on the same PC?
If they really don't then make a cable that taps wires TX, RD and Ground (on a 25 pin I think that's 2 3 and 7). Hook the taped lines to the com port on the other machine and you can monitor the traffic.

there is a program that allows you to do just that, and it's free. That program is called: "PortMon" and it comes in a suite of moitoring software such as FileMon, RegMon etc.

Hi to everyone....I have an opengl application contains a 3-D shape where the user can rotate it,translate it e.g.... Well my problem is that i want to click on lines and points of this grafic and show details for that point or item....I think is called hit test!!!!!Does anyone knows how can i do that or show me a link in web telling me how to do that, or just give me some simple steps!!!!!
Thanks u for ur time!!!!

Uh. Well. I don't know how to realize with OpenGL, but if you want to know something about OpenGL http://nehe.gamedev.net/[^] is a much better place to look at. There should be a forum, too.
I only now how you could realize it programming it all on your own in C++. Then you have to project the 3D-Scene on a 2D-Matrix and you store which points (perhaps as a vector linetest) are corresponding to which object.

Thanks for ur response!!!!That was my first decide to convert the 3-D to
2-D Matrix, but i think is so difficult because the objects rotates and that mean that the coordinates must change!!! I find a way to make it with glLoadName[] argument.....where every line and spot will be an index in that matrix.......Do u know anything about that????
Thanks!!!!!!!!!

No sorry. Yet I just did the rotation for myself and worked with the scene parallel to OpenGL (I wrote a "Level of Detail" appoximative collision detection for huge scene with a large amout of objects), so I just know the OpenGL basics and did the other work on my own.
