#include <iostream>

// pass by ref
void p(int (&r)[3])
{
for (size_t i = 0; i < sizeof(r)/sizeof(r[0]); i++)
{
std::cout << r[i] << ' ';
}
std::cout << '\n';
}

// pass by ptr
void p(int* r, size_t len)
{
for (size_t i = 0; i < len; i++)
{
std::cout << r[i] << ' ';
}
std::cout << '\n';
}

int main()
{
int m[] = { 1, 2, 3 };
p(m); // ref
p(m, 3); // ptr
return 0;
}
