int main(void)

{

//定义对象数组

    Coordinate *coorArr = new Coordinate[2];

    coorArr->m_iX = 1;

    coorArr->m_iY = 2;

    coorArr++;

    coorArr->m_iX = 3;

    coorArr->m_iY = 4;

    //coorArr[0].m_iX = 1;

    //coorArr[0].m_iY = 2;

    //coorArr[1].m_iX = 3;

    //coorArr[1].m_iY = 4;

//遍历数组，打印对象信息

for(int i = 0; i < 2; i++)

{

coorArr[i].printInfo();

coorArr-=2;

}

coorArr++;

delete []coorArr;

coorArr = NULL;

return 0;

}

循环里面指针要减2，不过最后结果会倒着打印出来。

 //定义对象数组

    Coordinate *coorArr = new Coordinate[2];
    coorArr[0].m_iX = 1;
    coorArr[0].m_iY = 2;
    coorArr[1].m_iX = 3;
    coorArr[1].m_iY = 4;

    //遍历数组，打印对象信息
    for (int i = 0; i < 2; i++)
    {
        coorArr[i].printInfo();
    }
    delete[]coorArr;
    coorArr = NULL;
    return 0;

要用coordinate[0].m_iX   coordinate[1].m_iX 这样的才能准确的给每个对象赋值吧
