#includeThis code example creates a list of MyClass pointers and adds three dynamically allocated objects to the list. When the clear function is called, all the objects are deleted from memory. The output of the code will show that the object constructors are called when they're created and the destructors are called when they're deleted.#include using namespace std; class MyClass { public: MyClass() {cout << "Object created!" << endl;} ~MyClass() {cout << "Object deleted!" << endl;} }; int main() { list
objectList; objectList.push_back(new MyClass()); objectList.push_back(new MyClass()); objectList.push_back(new MyClass()); objectList.clear(); return 0; }
