## C++傳遞陣列到函式範例：列印陣列元素

``````#include <iostream>

## C++傳遞陣列到函式範例：列印最小數

``````#include <iostream>

}
cout<< "Minimum element is: "<< min <<"\n";
}

``````Minimum element is: 10
Minimum element is: 5

## C++傳遞陣列到函式範例：列印最大數

``````#include <iostream>

cout<< "Maximum element is: "<< max <<"\n";

``````Maximum element is: 54
