[ test.Counter.cpp ] [ test.Circle.cpp ]

Experiment 1

Try to compile and run "test.Counter.cpp". Does it work? Does it fail? If so, fix it!

Experiment 2

Add a new function to the Count class and add statements that test it.

The header for the function is

 		void setValue(int v); // sets value to v

and a suitable test is

 		c.setValue(5);

 		assert(c.getValue() == 5 );

Add any other test you like... then add the function definition

 		void Counter::setValue(.....){....}

(fill in the blanks) and make it work.

Experiment 3

Try to compile and run "test.Circle.cpp". Does it work? You will need a calculator -- our machines have one: Activities -> Applications -> Accessories -> Calculator, or you can use Google in your browser!

How does it fail? Fix it (the error is subtle, be thoughtful)!

Finish all the experiments and get an a A.
