Question

C++：用循环语句编程打印如下矩阵：
1 0 1 2 3 4 5 6
2 1 2 3 4 5 6 0
3 2 3 4 5 6 0 1
4 3 4 5 6 0 1 2
5 4 5 6 0 1 2 3
6 5 6 0 1 2 3 4

#include <iostream>
using namespace std;

int main()
{
    int a[8] = {1, 0, 1, 2, 3, 4, 5, 6};
    for (int i = 0; i < 6; i++)
    {
        for (int j = 0; j < 8; j++)
        {
            cout << a[j] << " ";
            a[j] = (a[j] + 1) % 7;
        }
        cout << endl;
    }
    return 0;
