reference to an element of char array

[kox]

Hello. I'm learning about pointers. I'm wondering why reference to an element of char array doesn't give me address of this element.
For example:

char arr[]={ 'a', 'b', 'c', '\0' };
cout << &arr << endl;
cout << &arr[0] << endl;
cout << &arr[1] << endl;
cout << &arr[2] << endl;
cout << &arr[3] << endl;

It's output:

0x7ffff4ba8c30
abc  // should be 0x7ffff4ba8c30 ?
bc
c

It works with array of integers.

There is an overload for operator<<() that takes a const char * as its right hand operand and sends to the output stream the string that the pointer points to. If that overload was defined differently, you wouldn't be able to do this:

std::cout <<"Hello, World!\n"

You'd just get the address of the string.

To treat the pointer as a pointer, cast to void *:
cout << (void *)&arr[0] << endl;

Firstly the "&" is not reference here it is the "address of" operator

cout is treating the &arr[1] as "pointer to char" instead of pointer type

use

cout << cout << static_cast<const void*>(arr) << endl; 
cout << cout << static_cast<const void*>(arr+1) << endl;

Ok, thanks.
