C / C++ / MFC

typedef vector<Whatever> WhateverV;

int Store(Whatever const& w, WhateverV vw)
{
vw.push_back(w);
}

void test()
{
foo();
}

void test()
{
  Myclass* p = foo();

do something with "p" then

  delete p;
}

I've debugged the presented code step by step and witnessed that the compiler deletes p itself on exit from test() !

class MyTest
{
public:

   MyTest() { cout << "Creating MyTest " << this << endl; }
   MyTest(MyTest const & rhs) { cout << "Copy-Construct MyTest " << this << " from " << &rhs << endl; }
   MyTest& operator=(MyTest const & rhs) { cout << "Assign MyTest " << this << " from " << &rhs << endl; }
   ~MyTest() { cout << "Destroying " << this; }
}

MyClass * p1 = new MyClass;
MyClass temp = *p1;

MyClass * Get()
{
   MyClass * p = new MyClass;
   return p;
}

MyClass Get()
{
   MyClass * p = new MyClass;
   return *p;
}

void foo(MyClass*& p)
{
   p = new MyClass();
}

void test()
{
   MyClass* p
   foo(p);
   // Use the class using p->
   delete p;
}

void main()
{
   test();
}
