WebbTherefore, although function calls in C use pass-by-value semantics, arrays are in effect passed by reference. The total size of an array x can be determined by applying sizeof to an expression of array type. The size of an element can be determined by applying the operator sizeof to any dereferenced element of an array A, as in n = sizeof A[0]. Webb2 nov. 2010 · Is there anyway to use a "sizeof" in a pre-processor macro?No. The conditional directives take a restricted set of conditional expressions; sizeof is one of the things not allowed. Preprocessing directives are evaluated before the source is parsed (at least conceptually), so there aren't any types or variables yet to get their size. cinemark tambore ingresso
