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.
The hoover dam and Grand Canyon National Park are very good options. One of my favorite places is about 45 minutes to an hour south of flagstaff. Sedona is a beautiful place and there is plenty to do from hiking to jeep tours to spa weekends.
