WebOct 2, 2024 · The C implementation is required to convert the distance from bytes (or whatever units it uses) into elements of the appropriate type. If a is an array of double of eight bytes each, then a [5]-a [2] is 3, for 3 elements. If a is an array of char of one byte each, then a [5]-a [2] is 3, for 3 elements. Why would pointers ever not be just numbers? http://www2.maths.ox.ac.uk/~gilesm/cuda/lecs/lec5-2x2.pdf
