The latter only applies to array names: variables declared with subscripts (int A[twenty]). Due to semantics of C, it can be not possible to ascertain all the dimension of arrays through tips to arrays or Individuals designed by dynamic allocation (malloc); code like why not check here sizeof arr / sizeof arr (exactly where arr designates a pointer) will not perform For the reason that compiler assumes the size with the pointer alone is getting requested.
