Use of constructors

Lecture 4 - Slide 8 : 40

Use of constructors

We illustrate the use of overloaded constructors - using funny Point initializations

Four funny Point constructors:
- Point(): (0, 7) - default constructor
- Point(double x, double y): (x, y)
- Point(double x): (x, 20)
- Point(const Point& p): (p.x+1.0, p.y+2.0) - copy constructor

Class Point with a variety of constructors.

Funny implementations of the constructors.

Use of constructors - with local variables of class type.

Actual program output.

An additional Point construction attempt - a trap.

An additional Point construction attempt - with use of uniform default initialization.

Use of constructors with object on the free store
