c++编程，输入一个大于3的奇数，输出一下图案

#include<iostream>
using namespace std;

int main()
{
    int i,j,n,m;
    cin >> m;
    n = m/2;
    for(i=1;i<=n;i++){
        for(j=0;j<=n-i;j++)
            cout << " ";
        for(j=1;j<=i;j++)
            cout << j;
        for(j=i-1;j>=1;j--)
            cout << j;
        cout << endl;
    }
    for(i=1;i<=m;i++){
        cout << "1";
    }
    return 0;
}

#include <iostream>
