Pointers

Pointers and Memory Allocation

Pointers are declared by placing an * after the typename.
```
Time * deadline;
```
Pointers hold the location of an object, not the actual object itself.
To create a new object, you use the new command.
```
deadline = new Time;
```
You can also call the new command in conjunction with a constructor to initialize the object.
```
Employee* boss = new Employee("Lin, Lisa", 68000);
```
To access the object that a pointer points to, the object must be dereferenced:
- Use * to access the actual object.
- Use -> to access methods of the object.
```
raise_salary(*boss, 10);
string name = boss->get_name();
```

The dot operator has a higher precedence than the * operator:

string name = *boss.get_name(); // Error
string name = (*boss).get_name(); // OK
