Class and Pointers

[sammy]

I have my class defined as sample. I want to declare a pointer to an int member of class sample and also initialize the pointer to a member. Kindly tell me how I can achieve this. I know concepts of pointers and class separately but want to try out combining both in this example. Kindly help me out.

[hvg_99]

class sample{
public:
int i;
}

int main(){
// declare a pointer to a data member
int sample::*ptr=&sample::i;
}

Here 'i' is a member of sample class and ptr is a pointer to a member of sample class.

I hope i have cleared your doubt,

Regards,
Gayatri

It was a excellent explanation that clarified my doubt about declare a pointer to member of a class and also on initializing the pointer to the member. Kindly tell me whether we can handle pointers concepts in the same way as we handle in C or is there any restriction in C++ or any new feature related to pointer usage in C++ which is not in C.
