题解 | 利用指针遍历数组

#include <iostream>
using namespace std;

int main() {

    int arr[6] = { 0 };
    int* ptr = arr;

    int len = sizeof(arr) / sizeof(int);

    for (int i = 0; i < len; i++) {
        cin >> arr[i];
    }

    // write your code here......
    for (int i = 0; i < len; i++){
        cout << ptr[i] << " ";
    }

    return 0;
}
