Difference 1>
Reference must point to valid objects at the time of
declaration where pointer need not point to valid objects
at the time of declaration means
int nvalue=5;
int &rnvalue; //This is invalid.
int &rnvalue=nvalue; //This is valid.

But
int *rnvalue; //This is valid.
rnvalue=&nvalue;
Difference 2>
Pointer is a variable which holds the address of another
variable.
But Reference is another name of the same variable.
