Found this on Reddit: http://herbsutter.com/2013/05/28/gotw-6b-solution-const-correctness-part-2/

I was surprised to learn that these two function declarations generate the same function:

int f( int );
int f( const int );

I've always wondered is there an article on standard practice for the Const keyword. Thanks for finding.

If const is not utilized, the original passed variable will not be altered, however the passed value can be altered within the function it was passed to. If const is declared, neither the original variable nor the passed value can be altered within the function.

Or am I missing the point to this thread?

Spoiler

“Hello, ladies, look at your man, now back to me, now back at your man, now back to me. Sadly, he isn’t me, but if he stopped using ladies scented body wash and switched to Old Spice, he could smell like he’s me. Look down, back up, where are you? You’re on a boat with the man your man could smell like. What’s in your hand, back at me. I have it, it’s an oyster with two tickets to that thing you love. Look again, the tickets are now diamonds. Anything is possible when your man smells like Old Spice and not a lady. I’m on a horse.”

That's correct, the point was that the code generated is the same.
