Explanation / Answer

1.Parent/child

Explnation: Inheritance is nothing but when a subclass is inherited by a super class.So here child class is inherited by a parent class.So this relationship explains the inheritance concept.

2.The Laptop is a Computer. There is no relationship to a super computer.

A computer is nothing but general purpose programmble machine and according to specified set of instructions it carries out logical and arithmetic operations.
Coming to super computer these are are types of computers shows the best processing capacity and it is more exxpensive than other computer.These are the fastest a and biggest machines today

3.After the requirements are documented, the process of identifying classes can begin

After the requirements are documented, the process of identifying classes can begin. From the requirements the stright forward way of identifying classes is to highlight all the nouns.Here these tends to represnt objects, such as people, places and things.

4. Statement of work

5. When you need to create a specialized class from an existing class

Explanation: From an existing class will create a child class when the properties of parent class need to be useful for child class.So that inheritance relation will supports.

6.All of the above

10. Programming to an interface makes the code more logical

11. None of the above

In computer programming self documenting source code follows naming conventions and structured programming conventions enables use of system with out prior specific knowledge

12. Combine multiple classes in a same file to allow easy access
