Chapter 11 Exercise Set 0: Chapter Review¶

As you did back in the A more efficient increment exercise in chapter 8, rewrite the increment function from the Another example section more effeciently without iteration.
In the Initialize or construct? section, you defined a constructor for Times that had two integers and a double as parameters. The combination of function name and the ordered types of its parameters is known as the function signature. The C++ compiler uses this signature to determine which version of an overloaded function to call.

Try creating a new Time with this constructor by passing it three int arguments:
```
Time current_time(9, 14, 3);
```
What happens? Now define a new constructor with the following
```
Time(int h, int m, int s);
```
Print out a different message inside each constructor so you can see which one was called. Create current_time again and run your program. What happens?
Rewrite the distance function from Structues as parameters as a member function of the Point struct.

Overload the - operator for points, to support

Point p1(7, 4);
Point p2(3, 1);
Point p3 = p1 - p2;
cout << p3 << end;

which should print (4, 3).

Add two constructors to the Rectangle structs introduced in the Structures chapter with the following protoypes:

Rectangle::Rectangle(Point upper_left, double width, double length);
Rectangle::Rectangle(Point upper_left, Point lower_right);
