Basic C++ :: XOR Gates

XOR gate - Wikipedia, the free encyclopedia

C++ does not define a logical operator that performs an exclusive-OR operation,
usually referred to as XOR. XOR is a binary operation that yields true when and only one operand is true.

What you need:
A Brain,
Patience,
A C++ IDE,
The ability to read.

1. Create a new console application called XOR.cpp

2. Assuming there are two boolean values a XOR is constructed like this:

(p||q)&&(p && q)

3. Now enter this code into the main() function in your C++ program.
It demonstrates the XOR operation for 2 combinations of true/false values.

bool p, q; 


    p = true; 

    q = true; 


    cout << p << " XOR " << q << " is " << 

     (( p || q ) && ! ( p && q )) << "\n"; 


    p = false; 

    q = true; 


    cout << p << " XOR " << q << " is " << 

     (( p || q ) && ! ( p && q )) << "\n";

4. The output should look like this:

1 XOR 1 is 0 

0 XOR 1 is 1

Sorry, I didn't realise there was a tutorial section.

Don't worry! It will be moved soon...

C++ does support (bit-wise) XOR. It's ^ operator.
