Re: [Dev-C++] Memory

[Daniel G. <sp...@ho...>]

For C++ you must delete any objects you create with the new operator. 
Variables created normally will be destroyed when they go out of scope.

So
int main(int argc, char** argv)
{
   int SomeInt = 0;

   return 0;
}
// SomeInt has been destroyed.

or try
int main(int argc, char** argv)
{
   {
      // The { doesn;t do anything except limit
      // the scope of everything within.
      int SomeInt = 0;

   } // someInt now destroyed.

   return 0;
}


but if you do
MyClass* Ptr;   // Ptr can point to a MyClass object
Ptr = new Myclass;

//...

delete Ptr;        // Delete the object and free the memory.


This is because with 'new' you allocate memory at run time, not at compile 
time.
