question regarding pointer

Question

int a;
int *ptr;
ptr=&a;
cout<<"&a";

2nd program

int a ;
cout<<"&a";

are these 2 program same?

Answer 1

The output will be the same.

They both output the string: &a

If you want to output the memory address of a, do not use double quotes in the cout:

cout << &a;

Double quotes create a string literal.
