As long as you know the type of the inner-most element, you can do it. This excludes auto, but I think you usually know this. double x[4][5][6][7]; size_t n = sizeof(x) / sizeof(double); This hard-codes 'double', but should be good enough usually. Cheers, Alex -- <https://www.alejandro-colomar.es/>
