How can I change addresses of arrays with pointers ?

Question

For example, we have an array in heap. And we will reverse array. But we have to reverse addresses too.
Like this;
array [0]=0xbc1510 // address of array
array [1]=0xbc1514
array [2]=0xbc1518
//After Reversing
array [0]=0xbc1518
array [1]=0xbc1514
array [2]=0xbc1510
