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.
How do you measure the pitching distance for high school softball? The pitching distance is 40 feet from home plate to the back of the pitching rubber. For 18U Gold and collegiate softball the pitchers mound is 43 feet away. This is because pâ¦itchers throwing at these levels throw much faster than those at the lower levels, making it a lot harder for batters to identify pitches.
