New creates objects. Delete deletes objects. eg - int *x = new int; // Give me a new int eg - delete x; // Delete the int that was created These functions are useful because they allow you to allocate as much memory as you need (eg ask the user for how many numbers do they want to type in, allocate that many ints and then loop through and store the values). Note that there are two other operators, new[] and delete[] that are used for creating/deleting arrays. eg - int *x = new int[5]; // Give me 5 new ints eg - delete[] x; // Delete the 5 ints If you mix and match the different operators(eg new[] with delete) you may end up with memory leaks - delete only expects one object, so if you give it 10 objects created by new[] then it will only delete one.
