2.1.3. Thinking Procedurally

What is the first stage of thinking procedurally?

• Taking the problem defined by the user and breaking it down into its constituent parts

• Developing a solution

• Testing a solution

• Analysing a problem

What is the purpose of problem decomposition?

• To make complex problems easier to solve and more manageable by allowing tasks to be divided between a group of people according to individual skill sets.

• The process of separating ideas from specific instances of those ideas at work

• Any situation in the design or programming of a system when you would want more than one thing happening at the same time

• Letting the problem rot away

State another name given to top-down design.

• Stepwise refinement

• Problem Recognition

• Divide and Conquer

• Problem Decomposition

• Backtracking

What is the purpose of top-down design?

• Continually break problems down into subproblems until each subproblem can be represented as a single task and ideally a self-contained subroutine.

• The analysis of a large amount of data in a data warehouse to provide new information.

• An algorithm for finding a complete solution. This is a refined brute force methodology. It is a very general algorithm for finding all (or some) solutions to computational problems.

• The process of separating ideas from specific instances of those ideas at work

What are the benefits of using top-down design?

• Problems can be solved and modules developed by different people

• Tasks can be tested separately. Modules are self-contained

• Uses abstraction to create algorithms and prototypes

• Wireframe designs are required before development can take place

What sort of problems is top-down design suited to?

• Large, complex problems

• Small, complex problems

• Large, simple problems

• Small, simple problems

What is the second stage of thinking procedurally in software development?

• Identifying components of a solution

• Taking the problem defined by the user and breaking it down into its constituent parts

• Developing a solution

• Testing a solution

What are the lowest level subproblems in top-down design in code?

• self-contained modules or subroutines

• Machine Code

• High Level Language

• Flow Chart

What do software developers need to consider when recombining components of a solution?

• The order in which subroutines are executed, and how they interact with each other, based on their role in solving the problem.

• Who the original author of the component was

• Will they fit together

What must a software developers do before designing a subroutine to solve a particular problem?

• See whether it is possible for an already existing subroutine or module to be used.

• Taking the problem defined by the user and breaking it down into its constituent parts

• Developing a solution

• Testing a solution

• Analysing a problem
