Standard macro to calculate the number of elements in an array

Question

Is there something like this available in the C standard library:

#define sizeofarr(a)    ( sizeof(a) / sizeof(a[0]) )

if you have an array where the size is known at compile time, you can do it, but otherwise no — bruceg, Nov 02 '17 at 01:23
@bruceg `( sizeof(a) / sizeof(a[0]) )` works for VLAs too - array who size is not known at compile time. — chux - Reinstate Monica, Nov 02 '17 at 03:01

No. There is not something like that available in the C standard library.
