Write a C++ program which demonstrate the use of Bit-wise OR (|) use with pointers.

Use of Bit-wise Arithmetic operators with Pointers

We can perform Bit-wise operation between two pointers like:

Address1 & Address2 = Illegal

Address1 | Address2 = Illegal

Address1 ^ Address2 = Illegal

~Address = Illegal

Lets explain Bit-wise operator illegal use with the help of a C++ program

a. Write a C++ program which demonstrate the use of Bit-wise OR (|) use with pointers.  

#include<iostream>

using namespace std;

int main()

{

int x=10;

int y=20;

int *ptr1 = &x;

int *ptr2 = &y;

cout<<" Value of Bit-wise OR operator use with ptr1 and ptr2 "<< ptr1|ptr2;

return 0;
}

The above program output is tested on www.jdoodle.com

Output:

jdoodle.cpp: In function 'int main()':

jdoodle.cpp:9:70: error: no match for 'operator|' (operand types are 'std::basic_ostream<char>::__ostream_type {aka std::basic_ostream<char>}' and 'int*')

 cout<<" Value of Bit-wise OR operator use with ptr1 and ptr2 "<< ptr1|ptr2;

or

compile time error

b. Write a C++ program which demonstrate the use of Bit-wise AND (&) use with pointers.  

#include<iostream>

using namespace std;

int main()

{

int x=10;

int y=20;

int *ptr1 = &x;

int *ptr2 = &y;

cout<<" Value of Bit-wise OR operator use with ptr1 and ptr2 "<< ptr1 & ptr2;

return 0;
}

The above program output is tested on www.jdoodle.com

Output:

jdoodle.cpp: In function 'int main()':

jdoodle.cpp:9:71: error: no match for 'operator&' (operand types are 'std::basic_ostream<char>::__ostream_type {aka std::basic_ostream<char>}' and 'int*')

 cout<<" Value of Bit-wise OR operator use with ptr1 and ptr2 "<< ptr1 & ptr2;

or

compile time error
