大一小白，求大神给解个c++题

#include"iostream"

using namespace std;

class Marray
{
public:
    Marray(int n)
    {
        if (n < 0)
        {
            cout << "输入数组下标不合法" << endl;
            return;
        }

        Len = n;
        pArray = new int[n]{0};
        if (pArray == NULL)
        {
            return;
        }

        for (int i = 0; i < n; i++)
        {
            pArray[i] = i;//完成0~n的赋值
        }
    }
public:
    void Test()
    {
        int *tem = new int[Len]{0};
        int j = 0;
        if (tem == NULL)
        {
            return;
        }

        for (int i = 0; i < Len; i++)
        {
            if (pArray[i] % 2 != 0)//奇数
            {
                tem[j] = pArray[i];
                j++;
            }
        }
        for (int i = 0; i < Len; i++)//偶数
        {
            if (pArray[i] % 2 == 0)
            {
                tem[j] = pArray[i];
                ++j;
            }
        }
        for (int i = 0; i < Len; i++)
        {
            pArray[i] = tem[i];
        }
        print();
        delete[] tem;
    }
protected:
    void print()
    {
        for (int i = 0; i < Len; i++)
        {
            cout << pArray[i] << " ";
        }
        cout << endl;
    }
public:
    ~Marray()
    {
        delete[] pArray;
    }
private:
    int Len;//数组容量
    int *pArray;
};

int main()
{
    Marray array(100);
    array.Test();
    return 0;
}

很久没做这种题目了，暴力一些
