Hi Guyz
I have Assignment in c++ and it required to put the classes members in .h file
and creat the function in .cpp file
and the main function in .cpp also
((((#include "Name.h")))))
but it not woring however if the classes and the function inside the main.cpp it works fine
im using Dev c++ and VC++ the same issue i recieved

We may ask Chris to make a new forum, the 'I need help URGENT plz' one.

Well, you should go back a read your class notes; ask you classmates, friends, teacher, teaching assistants ...
This is very, very, very basic stuff you are asking.

Dude I know it basic and easy Q. but it confusing me

So what do have you in place so far? What compiler/linker error(s) are you getting?

[Linker error] undefined reference to `Date::getDate()'
[Linker error] undefined reference to `Date::showDate()'
ld returned 1 exit status
I must link the .ccp , .h with the mainCode but it's not working
how ever if I put the code in one main file it works fine

Is Date a class of yours? Are getDate() and showDate() static methods?

ya
the program ask the user to implemnt the date mm/dd/yy with function int getDate()
and the program should outputs the with void showDate()
but this two function are public members and the ipmlemntation in .cpp file
#include "stdafx.h"
#include "Date.h"
#include <iostream>
using namespace std;
int main()
{
Date d;
cout<<"Enter the date within formam mm/dd/yy\n";
cin>>d.month>>d.day>>d.year
d.getDate();
d.showDate();
system("pause");
return 0;
}
//Date.cpp function
#include "stdafx.h"
#include "Date.h"
using namespace std;
int Date::getDate() //(int month,int day,int year)
{
return(month,day,year);
}
void Date::showDate()
{
cout<<month<<"/"<<day<<"/"<<year<<endl;
}
//HEADER FILE
#ifndef DATE_H
#define DATE_H
class Date
{
public:
int month;
int day;
int year;
int getDate();
void showDate();
};
I think my problem in the passing arguments !!?

What is this?
dr.nokia wrote: cin>>d.month>>d.day>>d.year
Missing a semicolon.
dr.nokia wrote: d.showDate();
This statement is not doing anything useful.
dr.nokia wrote: I think my problem in the passing arguments !!?
No. Arguments are what get passed to functions/methods.
Other than the one syntax error, your code should compile and work as expected. It could be vastly improved, but that is another subject altogether.

Thanx Mr.Daived
i fixid the semicolon but it not working also 
i will try my best and thanx alot for ur help
good luck !!

What about a good C++ tutorial?
BTW you really need to read this [^], before posting.

Ｉ found the opencv source of cvcamshift.cpp .I have one problem of cvCamShift function in this file.That is how it change the weidth and hength and orientation .
In cvcamshift.cp:
m00 = moments.m00;
m10 = moments.m10;
m01 = moments.m01;
mu11 = moments.mu11;
mu20 = moments.mu20;
mu02 = moments.mu02;
if( fabs(m00) < DBL_EPSILON )
EXIT;
inv_m00 = 1. / m00;
xc = cvRound( m10 * inv_m00 + windowIn.x );
yc = cvRound( m01 * inv_m00 + windowIn.y );
a = mu20 * inv_m00;
b = mu11 * inv_m00;
c = mu02 * inv_m00;
/* Calculating width & height */
square = sqrt( 4 * b * b + (a - c) * (a - c) );
/* Calculating orientation */
theta = atan2( 2 * b, a - c + square );
/* Calculating width & length of figure */
cs = cos( theta );
sn = sin( theta );
rotate_a = cs * cs * mu20 + 2 * cs * sn * mu11 + sn * sn * mu02;
rotate_c = sn * sn * mu20 - 2 * cs * sn * mu11 + cs * cs * mu02;
length = sqrt( rotate_a * inv_m00 ) * 4;
width = sqrt( rotate_c * inv_m00 ) * 4;
IN a paper:(I am sorry ,It's not clear .But if you want I can send to you.)
The orientation (θ) of the major axis and the scale of the distribution are determined by finding an equivalent rectangle that has the same moments as those measured from the 2D probability distribution image (c.f. Horn, 1986). Defining the first and second moments for x and y
ΣΣ=xyyxIxM),(220
ΣΣ=xyyxIyM),(202
ΣΣ=xyyxxyIM),(11
The first two eigenvalues (the length and width of the probability distribution) are calculated in closed form as follows. From the intermediate variables a, b and c20020cxMMa−= −=ccyxMMb00112 20002cyMMc−=
We find the orientation of the equivalent rectangle −=−cab1tan21θ
The distances l1 and l2 from the distribution centroid (the dimensions of the equivalent rectangle) are given by, 2)()(221cabcal−+++= 2)()(222cabcal−+−+=
Where the extracted parameters are independent of the overall image intensity.
Thank you .I am looking forward to your answer.

Simply there is no question in your post: what did you intend to ask? Moreover could you please reformat it? As it stands, it is difficult to understand.

Hy folks,
I have a little question of reading out the amount of memory that one can use for a program.
I know there exists the method filling up the memory until you get an exception, but this isn't a nice way, right?
So my question: Is there a way to read out memory specs in windows and other platforms as well?
I was just wondering if one of you can thing of a nice platform independent function or approach to calculate the amount of memory available in the system.
Also I am interested to find out the amount of processors to calculate the amount of threads for that platform.
I am sorry for the leaking of knowledge. 
Cheers
