The contents ... There are two forms of static initialization: In practice: 1. Constant initialization is usually applied at compile time. Pre-calculated object representations are stored as part of the program image. If the compiler doesn't do that, it must still guarantee that the initialization happens before any dynamic initialization. 2. … See more After all static initialization is completed, dynamic initialization of non-local variables occurs in the following situations: If the initialization of a non … See more It is implementation-defined whether dynamic initialization happens-before the first statement of the main function (for statics) or the initial function of the thread (for thread-locals), or deferred to happen after. If the … See more The compilers are allowed to initialize dynamically-initialized variables as part of static initialization (essentially, at compile time), if the following conditions are both true: Because of the … See more
WebThe basic form of declaring a variable is: type identifier [= value] [, identifier [= value]]…]; OR. data_type variable_name = value; where, type = Data type of the variable. identifier = Variable name. value = Data to be stored in the variable (Optional field) Note 1: The Data type and the Value used to store in the Variable must match. WebApr 10, 2024 · It compiles in C++ because C++ needs to support dynamic initialization anyway, or you couldn’t have local static or non-local objects with non-trivial constructors. So since C++ has this complexity anyway, supporting that initialization like you show isn’t complicated to add anymore.
