Write a type definition for a type called NumberPtr that will be the type for pointer variables that hold pointers to dynamic variables of type double. Also, write a declaration for a pointer variable called myPoint, which is of type NumberPtr.
What will be an ideal response?
```
typedef double
NumberPtr myPoint;
```
To write a type definition, of a name, declare the name to have the type you want the
name to carry after the type definition. Then put the keyword
```
typedef double * NumberPtr; // NumberPtr is the type
// pointer to double
```

As public-key cryptography is computationally intensive and drains the battery of Barack's device, he comes up with an alternative approach. First, he shares a secret key k with Hillary but not with Bill. Next, together with a joke x, he sends over the value d = h(k||x), where h is a cryptographic hash function. Does value d provide assurance to Hillary that Barack is the author of x and that x
was not modified by Bill? Justify your answer. What will be an ideal response?
