您怎么知道您有内存泄漏?

如果您具有类(和构造函数)代码，那么应该很容易跟踪代码并查明内存分配，更重要的是，不存在的内存解除分配.

如果将类放在一个简单的项目中并在堆栈上创建该类的实例并正常退出进程，它会泄漏吗? (即调试器是否在调试会话结束时列出了内存泄漏?)

例如:

How do you know you have a memory leak ?

If you have the class (and the constructor) code then it should be easy to trace the code and pin-point the memory allocations or more importantly, the non-existant memory de-allocation.

If you put the class in a simple project and create an instance of the class on the stack and exit the process normally, does it leak ? (i.e. is the debugger listing memory leak at the end of the debuggin session?)

for example :

class YouClass;

int main(...)
{
  YourClass yourClass;

  return 1;
}

会泄漏吗?

如果使用new在堆上分配，是否使用delete删除内存?

does that leak ?

if you allocate on the heap with new, do you delete the memory with delete ?

class YouClass;

int main(...)
{
  YourClass* yourClass = NULL;
  yourClass = new YourClass;

  delete yourClass;
  yourClass = NULL;
  return 1;
}

如果简单程序泄漏，请检查类和轨道分配，以及取消分配，尤其是在destructor中.

最多

If the simple program leaks, check the class and track allocation, and also de-allocation, especially in the destructor.
