我现在已经坐了好几个小时了，这让我疯了。我是新c ++所以如果除了memoryleaks之外的其他东西是错的，我很想知道！ ：D
问题是，如果我成为一名新教师/助理/ TA并打印出来，我会得到：
{212} normal block at 0x005694B0, 8 bytes long.

如果我继续重复它只是堆积起来，我会感激所有帮助！ ：d

答案 0 :(得分：2)
你永远不会delete你的阵列。无论如何你应该使用矢量。
答案 1 :(得分：0)
基本上，对于您制作的每个new，您需要在不再需要该对象时使用delete。
这样做可以释放内存。如果你不这样做，你就会永远不断地增加分配的记忆。
答案 2 :(得分：0)
只要您动态分配内存并且不释放内存，就会发生内存泄漏。这意味着对于程序中显示的每个new，必须存在相应的delete，否则您将泄露内存。
您的代码中有很多delete已被注释掉（例如，tmp）。所以，我们肯定知道这些分配正在泄漏。
同样，您为swapper分配的内存未被释放（至少第一次通过循环）。此外，即使您调用delete [] work，也不是delete数组中的各个元素，这些元素也是动态分配的。
由于所有这些分配都发生在循环中，因此难怪你有这么多泄漏！
