C++练习：返回数组的引用

#include <iostream> using std::cout; using std::endl; // get returns a reference to an element in the given array int &get(int *arry, int index) { return arry[index]; } //返回给定数组元素的引用 int main() { int ia[10]; // array of ten uninitialized ints for (int i = 0; i != 10; ++i) get(ia, i) = i; // call get to assign values to the elements for (int i = 0; i != 10; ++i) // print the elements cout << ia[i] << " "; cout << endl; return 0; }
