what is a good rule of thumb for sizing a struct in c/c assuming that the struct is optimally set up? group of answer choices count all the bytes of the data in the struct. find the nearest power of 2, 4 or 8 based on the largest data type in your struct. if the total number of bytes is larger than that power, then the struct will be the next power in size. count all the bytes of the data-types in the struct. find the nearest power of 2, 4 or 8 based on the largest member in your struct. if the total number of bytes is larger than that power, then the struct will be the next power in size. count all the bytes of the data in the struct. find the nearest power of 2 based on the largest array in your struct. if there isn't an array use the largest variable. if the total number of bytes is larger than that power, then the struct will be the next power in size. the largest data-type in your struct raised to the power of how many members are in the struct.
