3.0 Basic Usage of Class

Well, the week I tried to use some class things.

Following is parts of my exercising codes.

• Definig my class named Time

　　　　

Note that CNT was a static member of this class to count the number of

Instances created.

• Constructors & Overloading

　　　

As can see, the 2nd one is a Copy Constructor. And since both of

The constructors has same name but different parameters, they

is also kind of overloading.

• Pass by Values OR References

　　

When passing parameters, ref was needed in front of value types-pass by

Reference While, it's not necessary if your pass an object (the output would be post

Later).

• Other Member Functions of Class

　　

These functions is used to display the contents of the instances.

----------so Much about the time class---------

Now, let me write some codes to test the time class.

• Creating Objects

　　

Create objects T1 and T2(with copy constructor)

• Function Testing

　　

I first invoked getbirthtime, passing an object, then invoked getbirthtime

Secondly, passing value types by reference.

---------------so Much for Test---------------

In the end, let's has a look at our Output ...

　　

Pay attention to the change of the CNT (static member);

Also, we'll find the amazing effect of passing by reference.
