Unused parts of an implicit instantiation may be ignored, but by explicitly instantiating, you are forcing it to handle the whole thing. Not that a single instantiation is likely to take a measurable amount of time, anyway. WebApr 19, 2024 · Initializer List is used in initializing the data members of a class. The list of members to be initialized is indicated with constructor as a comma-separated list followed by a colon.
