C++二维数组动态分配内存

演示了结构体与普通二维指针的动态分配

#include "stdafx.h"

struct POINT{
  double x,y;
};

int _tmain(int argc, _TCHAR* argv[])
{
  int **pData;
  POINT ** pPoint;
  int iCol = 5;//列数
  int iRow = 5;//行数
  pData = new int*[iRow];
  pPoint = new POINT*[iRow];


  for(int i = 0;i < iRow;i++){
    pData[i] = new int[iCol];
    pPoint[i] = new POINT[iCol];
  }


	return 0;
}
