For each of the following, write a statement that performs the specified task. Assume that dou- ble variables number1 and number2 have been declared and that number1 has been initialized to 7.3.

Question

a) Declare the variable doublePtr to be a pointer to an object of type double and initialize the pointer to nullptr.
b) Assign the address of variable number1 to pointer variable doublePtr.
c) Display the value of the object pointed to by doublePtr.
d) Assign the value of the object pointed to by doublePtr to variable number2.
e) Display the value of number2.
f) Display the address of number1.
g) Display the address stored in doublePtr. Is the address the same as that of number1?

Answer 1

```
a) double* doublePtr{nullptr};
b) doublePtr = &number1;
c) cout << "The value of *fPtr is " << *doublePtr << endl;
d) number2 = *doublePtr;
e) cout << "The value of number2 is " << number2 << endl;
f) cout << "The address of number1 is " << &number1 << endl;
g) cout << "The address stored in fPtr is " << doublePtr << endl;
Yes, the value is the same.
