In the below programme i use one boolean variable named check , which is being accessed inside main function by two objects of Tst1 and Test2 . But the value of check variable is not maintained in the programme . we can use static but i want to know some alternative way ..could anyone give me some hints on it ? Thanks in advance .

Inside jointdeatils.h

#pragma once

class Jointdetails
{
public:
    Jointdetails(void);
    ~Jointdetails(void);
    bool check;


};

Inside jointdeatils.cpp

#include "Jointdetails.h"

Jointdetails::Jointdetails(void)
{
    check = false ;
}

Jointdetails::~Jointdetails(void)
{
}

Inside analyzer.h

#pragma once
#include "Jointdetails.h"
class Analyzer
{
public:
    Analyzer(void);
    Jointdetails* GetJointDetails();
    Jointdetails* m_ptheCTJointDetails;
    ~Analyzer(void);
};

Inside analyzer.cpp

#include "Analyzer.h"
#include "stddef.h"
Analyzer::Analyzer(void)
{
    m_ptheCTJointDetails = new Jointdetails();

}

Analyzer::~Analyzer(void)
{
}
Jointdetails* Analyzer::GetJointDetails()
{

    if(m_ptheCTJointDetails) 
        return m_ptheCTJointDetails;
    else
        return NULL;


}

Inside Test1.h

#pragma once
#include "Analyzer.h"
class Tst1
{
public:
    Tst1(void);
    Analyzer *analyzer1 ;
public:
    ~Tst1(void);
};

Inside Test1.cpp

#include "Tst1.h"

Tst1::Tst1(void)
{
    analyzer1 = new Analyzer ;
}

Tst1::~Tst1(void)
{
}

Inside Test2.h

#pragma once
#include "Analyzer.h"
class Test2
{
public:
    Test2(void);
    Analyzer *analyzer2 ;
public:
    ~Test2(void);
};

Inside Test2.cpp

#include "Test2.h"

Test2::Test2(void)
{
    analyzer2 = new Analyzer ;
}

Test2::~Test2(void)
{
}

Inside main.cpp

#include "Test2.h"
#include "Tst1.h"
#include "stdio.h"

int main()
{
    Tst1 *test1 = new Tst1 ; //check = false
    Test2 *test2 = new Test2 ; //check = false
    test1->analyzer1->GetJointDetails()->check = true ;
    if(test2->analyzer2->GetJointDetails()->check )
        printf("Check value is changed");
    else
        printf("Check value is not changed");
        return 0 ;
}
