c++ - C++：删除动态分配的类时，不在堆上的私有成员也会被删除吗？

Question

例如，假设您有：

Class Test
{
     public:
     Test();
     private:
     int x = 0;
     int y = 3;
}

您使用类似的东西声明一个 Test 实例

Test * RRR = new Test();

假设在您键入的行的某个地方

delete RRR;

这是否也会删除 x 和 y 占用的内存？

Answer 1

the short answer is yes, but strictly speaking, x and y are not deleted. The memory they tak will be released, because they are data members of the struct.

Even you don't define a destructor, the compiler will synthesized a default destructor for you, which will release the memory that the struct takes.
