In 1998, the ISO working group standardized C++ for the first time as ISO/IEC 14882:1998, which is informally known as C++98. In 2003, it published a new version of the C++ standard called ISO/IEC 14882:2003, which fixed problems identified in C++98.
The Grand Canyon South Rim is just 119 miles from Sedona. About 2 hours from Sedona by car or on a guided van tour, you can see some of the world's most awe-inspiring sites on an 8 to 10-hour day trip. Unless you plan to hike down to the Colorado River and back up, one day is plenty to see Grand Canyon.
You'll pass within an hour's drive of the Grand Canyon from Williams, AZ and further west you could take a detour to see Hoover dam or even Las Vegas (I don't know if you have hours or days for this Sedona - LA trip). If you have just a few extra hours I'd personally just take the south route and push on through.
