The dimensions of an element may be determined by implementing the operator sizeof to any dereferenced component of x, as in n = sizeof *x or n = sizeof x, and the number of aspects within a declared array A is often decided as sizeof A / sizeof A. The latter only relates to array names: variables declared with subscripts (int A[twenty]). A result of the semantics of C, it's not possible to find out your entire sizing of arrays via tips to arrays or People produced by dynamic allocation (malloc); code for example sizeof arr / sizeof arr (in which arr designates a pointer) will not likely work For the reason that compiler assumes the dimensions in the pointer alone is becoming asked for.
