Hi,

1. Classes that are linked through inheritance relationships form an inheritance hierarchy. (Original) This seems OK.

Is #1 the same as this:

2. An inheritance hierarchy is classes that are linked through inheritance relationships. No. If you want to say this, say something like

An inheritance hierarchy is formed by/consists of classes that are linked through inheritance relationships. So, the problem is with 'is'. You could also say '...is defined as a set of ....'

Your explanation would also have to show where the hierarchical aspect comes from. It suggests that all the classes are not equal or at the same level.

Best wishes, Clive

PS Sorry, I forgot to look at No. 3!

3. An inheritance hierarchy is relationships that classes are linked.

Well, much the same comments apply. Say, for example,

An inheritance hierarchy consists of relationships between classes that are linked (through inheritances).

Are you learning C++?

The one numbered "2" is closer to what the original text is saying. It's saying that an inheritance hierarchy is created when you have different classes and these classes are related to one another by inheritance relationships. These classes and their relationships taken as a whole form the hierarchy.
