VC中动态申请和释放二维数组 用new delete

#define ROW 100
#define COL 200
#define T char (int,float,....) //通用数据类型
T ** pTemp ;
*pTemp = new T[ROW] ;
for (int i = 0 ; i < COL ; i ++)
   pTemp[i] = new T[COL};

/////////////////delete
for (int i =0 ; i < COL ; i ++)
    delete [] pTemp[i] ;
delete [][]pTemp ;

以图像为例
分配：
int height = value1;//value is used to allocate memory
int width = value2;
LPBYTE *lpImage;
lpImage = new LPBYTE[height];
for(int i = 0; i < height; i++)
   lpImage[i] = new BYTE[width]
释放：
for(int i = 0; i < height; i++)
   delete [] lpImage[i];
delete[] lpImage;
这样应该是对的，只是我没有加分配内存失败的错误处理。
