getting the type of element from array C -

i wondering if possible in c type element in array. have following code, have manually specify type, remove second argument.

#define foreach( func, type, list)do {\     int num_elements = sizeof(list) / sizeof(type);\     int iter;\     for( iter = 0; iter < num_elements; iter++)\         func(list[iter]);\     }while(0)  void display(int n) {     printf("\n%d\n", n); }  int main(void){     int list [] = { 1,2,3,4,5,6,7,8,9,10};     foreach(display, int, list);     return 0; } 

for purpose of question - can use sizeof operator on elements of array -

sizeof(list[0]) 

if using gcc (or gnu), there extenstion called typeof. can

sizeof(typeof(list[0]))  

but c way of doing directly use sizeof element.
