void funct()

{cout<<"Testing..."<<endl;};

};

 

// const and volatile...

const volatile int* Test1;

 

// const...

const int* Test2;

 

void TestConstVol()

{

One Test3;

// remove const...

const_cast<One>(Test3).funct();

// remove const and volatile...

const_cast<int> (Test1);

}

 

int main(void)

{

TestConstVol();

 

return 0;

}
