分享new与delete使用的问题
写了一段程序用new 和 delete分配释放内存，可是运行时发生内存泄漏。那位高手指点一下哈！谢谢
//记录直线坐标
LinePointX = new int[LinePnum];
LinePointY = new int[LinePnum];
//记录直线点值数组的起始点指针
//记录直线点值数组的起始点指针
//int* BakX = LinePointX;
///int* BakY = LinePointY;
int pointcount = 0;
for(j = 0; j <lHeight; j++)
{
for(i = 0;i <lWidth; i++)
{
// 指向缓存图像倒数第j行，第i个象素的指针
lpDst = (char *)lpNewDIBBits + lLineBytes * j + i;
if(0 == *lpDst)
{
*(LinePointX + pointcount) = i;
*(LinePointY + pointcount) = j;
pointcount++;
}
}
}
//计算子线斜率和截距
//Min2Method(xyTopX, xyTopY, LinePointX , LinePointY , LinePnum);
//?????????????????????????????????????????????????????????????????????????
//LinePointX = BakX;
//LinePointY = BakY;
delete []LinePointX;
delete []LinePointY;
//记录直线坐标
LinePointX = new int[LinePnum];
LinePointY = new int[LinePnum];
//记录直线点值数组的起始点指针
//记录直线点值数组的起始点指针
//int* BakX = LinePointX;
