1. How Dynamic Memory Works with Memory Diagram CSCE 121

2. output heap identifier stack

3. output int main() { int i = 14; int* k = &i; k = new int(3); delete k; Date* w = new Date(7, 7, 2015); delete w; w k 14 i w = nullptr; } heap identifier stack

4. output int main() { int i = 14; int* k = &i; k = new int(3); delete k; Date* w = new Date(7, 7, 2015); delete w; w k 14 i w = nullptr; } heap identifier stack

5. output int main() { int i = 14; int* k = &i; k = new int(3); delete k; Date* w = new Date(7, 7, 2015); delete w; w 3 k 14 i w = nullptr; } heap identifier stack

6. output int main() { int i = 14; int* k = &i; k = new int(3); delete k; Date* w = new Date(7, 7, 2015); delete w; w 3 k 14 i w = nullptr; } heap identifier stack

7. class Date { public: }; int month; int day; int year; // constructors Date(); Date(int month, int day, int year); // accessors and mutators int getMonth(); void setMonth(int month); int getDay(); void setDay(int Day); int getYear(); void setYear(int year); // methods void printDate();

8. output int main() { int i = 14; int* k = &i; month 7 day 7 k = new int(3); 2015 year delete k; Date* w = new Date(7, 7, 2015); delete w; w 3 k 14 i w = nullptr; } heap identifier stack

9. output int main() { int i = 14; int* k = &i; month 7 day 7 k = new int(3); 2015 year delete k; Date* w = new Date(7, 7, 2015); delete w; w 3 k 14 i w = nullptr; } heap identifier stack

10. output int main() { int i = 14; int* k = &i; month 7 day 7 k = new int(3); 2015 year delete k; Date* w = new Date(7, 7, 2015); delete w; w 3 Dangling Pointer k 14 i w = nullptr; } heap identifier stack
