Your pop function destroys the entire stack. It deletes the tmp node (by calling the Stack destructor), which still points to the new next. And since the Stack destructor calls delete on next, you get a mess of multiple destructor calls on the same objects. JMA beat me to it by a few seconds, so … Read more
Passing an instance of a class by value invokes the copy constructor. The compiler implements the copy constructor by default (essentially a memberwise copy after invoking copy constructors of any base classes) if the class definition does not explicitly supply one. This compiler-generated copy constructor will not call one of the other constructors you have … Read more
Examples When a variable goes out of scope void foo() { MyClass C; C.callSomeMethod(); } // C is here going out of scope or a dynamically allocated variable is explicitly deleted using the delete keyword void foo() { MyClass* C = new MyClass; // allocating on heap delete C; // deleting allocated memory … } … Read more
You should call Dispose(). Even if that doesn’t mean all memory gets freed immediately, all resources opened by the form (timers, files, etc.) should be closed then, if the form is programmed properly. Of course, the form will also be disposed of automatically when the GC runs the next time, but you can make it … Read more
new Element called, therefore owned by List, so only List can delete Element. List_iter doesn’t require a destructor because it only contains a pointer. solved Class destructor, runtime error: Unhandled exception – Stack overflow
The first Ghost is the PacMan member blinky. About the last order: Destroying pm1 exectutes ~PacMan(){ if (inky!= NULL) delete inky; cout <<“~PacMan()” << endl; } and then blinky is deleted too. If you want the opposite order, you’ve to write it here. solved The order of destructor
No, the destructor (~myClass) just does the stuff you want him to do when an object is no longer needed, like freeing resources (files, connections, …). Its the opposite of the constructor (myClass), where you set up your object (getting connections, etc). The GC removes all pointers to the myClass-object when it goes out of … Read more
Since you said you use dll_export, the cause of corruption can be one or more of the following: The application and DLL were not compiled with the same compiler options in terms of code generation. The application and DLL are using different heaps at runtime. For the first item, you must make sure that the … Read more
