  • define an array dip[0], dip[1] .... Commented Jun 14, 2022 at 6:42

    As for the "risk" of an array being created in SRAM, that would anyway be destroyed when the function in which it is defined, typically setup(), exits. If you explicitly define an array, you can still scan it with a C++11 range based for loop, which may improve the program's aesthetics. Commented Jun 14, 2022 at 10:16
