看清空格，用二维数组！

Answer 1

#include<iostream>
using namespace std;
int main()
{
    int n;
    cin >> n;
    int* m = new int[n * n];
    for (int i = 0; i < n; ++i)
    {
        for (int j = 0; j < n; ++j)
        {
            m[i * n + j] = i + 1 + 5 * j;
        }
    }
    for (int i = 0; i < n; ++i)
    {
        for (int j = 0; j < n; ++j)
        {
            cout << m[i * n + j] << ' ';
        }
        cout << endl;
    }
    delete[] m;
    return 0;
}
