C++ 创建动态二维数组

方法一（适用于数组维度不固定为var）：e.g.：

int** a;

a = new int*[var1];

for (int i =0; i < var1; i++)

{

        a[i] = newint[var2];

}

// delete

for (int i = 0; i < var1; i++)

{

        delete []a[i];

}

delete []a;

 

方法二（适用于数组长度固定为const）：e.g.：

int  (*a)[10];

a = new int[5][10];

// delete

delete []a;
