code. You've chosen to use heapsort, which allows you to easily compute a progress percentage. You also implemented a cache which lets you hold the top elements of the heap in memory. Accesses using the memory cache are much faster than accesses that need to be done on the file...

because of whole-program memory leaks 第6行显示我们程序有1块16字节的空间泄漏。第7到第9行,展示了泄漏处的调用堆栈。但是这个信息展现方式并没有直接指出问题产生的行数。我们可以使用其提示的第14行指令,调用可视化工具 在这里插入图片描述 如此,我们便可以清晰的知道,leak.cpp第5行代码申请的空间存在内存泄漏...
