The size of a component can be based on making use of the operator sizeof to any dereferenced factor of x, as in n = sizeof *x or n = sizeof x, and the volume of factors inside of 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). Because of the semantics of C, it is actually not possible to determine the whole dimensions of arrays by way of tips to arrays or Individuals established by dynamic allocation (malloc); code which include sizeof arr / sizeof arr (where by arr designates a pointer) will likely not do the job For the reason that compiler assumes the size from the pointer itself is getting asked for.
