For C++ it's Visual Studio and gcc, both are far ahead of the standard with experimental technical specifications: gcc has concepts, transactional memory, and special math, msvc has modules, coroutines, and parallelism (and concepts are promised soon), both have filesystem. Clang has none of that at the moment.
The 12-inch ball is the standard for slow-pitch softball. The ball is a little softer than the 11-inch version. The softness and its size, which makes it slightly harder to throw than a smaller ball, slows the speed of the game just a little bit compared to a game using an 11-inch ball. The fielders wear gloves.
The ISF recognizes three pitching styles: fast pitch, modified fast pitch, and slow pitch. Fast pitch is considered the most competitive form of softball. It is the form of softball that was played at the Olympic Games in 1996, 2000, 2004, and 2008. The fast pitch style is also used in college softball and international competition. Pitchers throw the ball with an underhand motion at speeds up to 75 miles per hour (121 km/h) for women and up to 85 miles per hour (137 km/h) for men. The pitching style of fastpitch is different from that of slowpitch softball.
