WebStatic casting converts one data type to another compatible data types (example string to int) As the name says ‘Static’, the conversion data type is fixed Static casting will be checked during compilation, so there won’t be run-time checking and error reporting Casting is applicable to value, variable or to an expression WebThe main reason is that classic C casts make no distinction between what we call static_cast<>(), reinterpret_cast<>(), const_cast<>(), and dynamic_cast<>().These four things are completely different. A static_cast<>() is usually safe. There is a valid conversion in the language, or an appropriate constructor that makes it possible.
