when you define No initialization type variables (such as int i;), the System It 's possible . will be implicitly initialized for us. It depends on the type of the variable and where we define it , as to whether the system will implicitly initialize

Static_cast (exdlvssion)Static_cast is much like the old-fashioned type conversion in the C language. It can convert between the underlying types, as well as the type conversions of constructors or user-defined type conversion operators with the
