Dynamic Memory Allocation

You need:

1. a pointer for the data type that will occupy the memory whose address you will point to

int* p;

1. if the pointer is already pointing at another already allocated memory, deallocate it
2. allocate memory and set the pointer to its address
3. use the memory
4. when you are done, deallocate it

delete[] p;
