Pointer offset for C + +

Suppose a class is defined as follows:
Class ob{
Public
Ob (): A (1), B (10) {}
int A;
Private
int b; };
?? Try to make a program, use the pointer offset method to access a to get
The value of B.
This question is not quite clear? Do you want to make up a class of b[10] arrays? Or what does that mean?

For:

A and B members of class OB are next to each other, so: the address of A and sizeof (int) is the address of B.

OB ob;

int *p=&ob.a+sizeof (int);

int t=*p;//Here, that's the value of ob.b.
