Classes:
A great deal of the rest of our C++ workshop will be understanding,
exploring and debugging Classes. In this section, I just want to take
a quick pass at them in order to complete the data types section of the
workshop. Classes are similar to structs and unions in that they have
similar syntax and can share similar functionality. They also create
new data types. In fact, they are the data type creator extraordinaire.
Classes need to be declared, defined, and implemented. The have a lot
of language magic to make them work, and their detail study is all but
necessary to become a good C++ coder. At their simplest level they look
like this:
Class Declaration:
Class myclass;
Class Definition:
Class myclass {
public:
member 1;
member 2;
private:
exclusive member one;
exclusive member two;
};
//Don't Forget the Semi-colon
myclass apples;
myclass apples("optional arguments");
myclass fruit = myclass("optional arguments");
myclass apples = "only one single argument";
Members that are public can be accessed like a struct:
int somevar = fruit.member1;
myclass * classptr = &fruit;
int somevar = classptr->member1;
private members can not be accessed from the outside of the class.
This is all I'll say about classes for the time being. Next is flow
control operators and structures.
