// If "const" is to the LEFT of "*" it applies to the object being pointed at
// If "const" is to the RIGHT of "*" it applies to the variable holding the pointer address

const T* ptr;  // object is immutable
T const* ptr;  //   "

T* const ptr;  // 'ptr' cannot be changed to point to a different address, but object is not immutable
               // (i.e. the variable is const, not the thing it points to)

const T* const ptr;  // object is immutable AND 'ptr' cannot be changed to point to a different address
