In this lab you will learn how to use classes.

Discussion

Topics:

Classes vs. C Structures
Dog class (Dog.cpp, Dog.h)

C++ Classes Assignment: Dog

Your assignment is to learn how to use the Dog class (Dog.cpp, Dog.h).

Assignment: Write a main() function, in a file called Lab3.cpp, that uses the Dog class in the following ways:

Create at least two different dogs
Give the dogs to people
Abuse and pat the dogs several different times
Talk to the dogs

As you go through these actions, use the appropriate accessors to show information about the dog as it changes. You should not have to modify the Dog class.

Compiling: To compile your assignment, use the following commands:

g++ -ansi -Wall -c Dog.cpp
g++ -ansi -Wall -c Lab3.cpp
g++ -ansi -Wall -o Lab3 Dog.o Lab3.o

Sample Output:
Here is a sample output. Note that the assignment directions require you to do more than this.
