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.

Question

What will be an ideal response?

Answer 1

```
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 in front. So:
double * NumberPtr;//NumberPtr is a pointer to double.
Then put the keyword typedef in front:
```
typedef double * NumberPtr; // NumberPtr is the type
// pointer to double

```
