The software for dynamic object initialization using the … 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-local variable with static or thread storage duration exits via an exception, … 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 … 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 rule above, if initialization of some … See more
