Initializing pointer to pointer to const float etc. using new operator

Question

Consider the following declarations :

const float** b;
const float* const* c;
float* const* d;

First off all I want to make sure that :

• b is a pointer to pointer to const float .

• c is a pointer to const pointer to const float .

• d is a pointer to a const pointer to float .

Now my question is how can I initialize each pointer using new operator ?

Answer 1

const float** b = new const float*();
const float* const* c = new const float*(nullptr);
float* const* d = new float*(nullptr);

the type with one less indirection and set values if they point on const
