Question In a class, there is a reference or pointer of an
object of
another class embedded, and the memory is either allocated
or assigned to the new object created for this class. In
the constructor, parameters are passed to initialize the
data members and the embedded object reference to get
inialized. What measures or design change should be advised
for proper destruction and avioding memory leaks, getting
pointers dangling for the embedded object memory
allocation? Please suggest.

There is something to be taken care in destructor, in copy
constructor, suppose the memory is assigned to the embedded
member object pointer with the parameter passed value, but
if some other objects of different class also are pointing
to this memory, then if some one deletes the object then
this class member pointer object will become dangling, or
if the object is not deleted properly then there will be
memory leak. Please suggest the design change required to
handle or avoid this situation

this is to swap to strings....but in output the whole
strings are swapped leaving first as it is...why it is so
#include<iostream.h>
int main()
{
char a[]="ajeet";
char b[]="singh";
long x=*a;
long y=*b;
cout<<x<<":"<<y;
x=x+y;
y=x-y;
x=x-y;
*a=x;
*b=y;
cout<<x<<":"<<y;
cout<<&a<<endl;
cout<<&b<<endl;
}
