1、例如

输出：2 3 4
          5 6 7
输入：9
          18

2、残缺代码如下

2.1 C++版本

#include <iostream>#include <cstring>using namespace std;int a[2][3];int res[2];void Sum(int (*p)[3], int total[], int n){    for(int i = 0; i < n; i++)    {        for(int j = 0; j < 3; ++j)             total[i] += p[i][j];    }}int main(){    for(int i = 0; i < 2; ++i)         for(int j = 0; j < 3; ++j)             cin >> a[i][j];    Sum(a, res, 2);    for(int i = 0; i < 2; ++i)         cout << res[i] << endl;        return 0; }

2.2 C语言版本

#include <stdio.h>int a[2][3];int res[2];void Sum(int(*p)[3], int total[], int n){    for (int i = 0; i < n; i++)    {        for (int j = 0; j < 3; j++)            total[i] += p[i][j];    }}int main(){    for (int i = 0; i < 2; i++)        for (int j = 0; j < 3; j++)            scanf_s("%d", &a[i][j]);    Sum(a, res, 2);    for (int i = 0; i < 2; i++)        printf("%d\n", res[i]);    return 0;}
