Randomly Intermittent Thoughts

    Thoughts I have pondered, but may not be wholely original…

    XOR in C++

    Final Recommendation:

    1. // 'a' and 'b' are some sort of integer type.
    2. // the double NOTs coerce to a standard boolean type
    3. // (compiler dependent)
    4. !!a ^ !!b

    Thankfully Java is easier

    1. // 'a' and 'b' are of boolean type
    2. // yay, no coercion necessary!
    3. a ^ b

    I didn’t know that the ^ operator was overloaded to handle Booleans, until I needed it a few weeks ago.
