Example

class MyClass { public: MyClass(int initnum) {    num = new int[initnum]; } ~MyClass() { } private: int *num; };

Solution

In the destructor, delete all  memory references that are initialized in the constructor. class MyClass { public: MyClass(int initnum) {    num = new int[initnum]; } ~MyClass() {    delete [] num; } private: int *num; };
