C++ call function with reference to array of const integers -

lets have these 2 function definitions:

int* first(int const (& array)[], int const size); void second(int const array[], int const size); 

and @ implementation of second want make call first this:

void second(int const array[], int const size) {     int* = first(*array, size); } 

thats when compiler tells me: "no matching function call 'first'". correct way call first second in case?

if have use arrays, suggest using std::array:

#include <array>  template<size_t n> int first(std::array<int, n> const& array) ;  template<size_t n> void second(std::array<int, n> const& array) {     int = first(array); }  int main() {    std::array<int, 3> = {1,2,3};     second(a); } 

if have array dynamic size, free burden of manually managing array , use std::vector instead.
