C++ Programming

1. Discuss why naming conventions are important and why programmers should consistently follow them. Include in this discussion problems that could arise in naming variables if one convention is not followed. 2. Why is it important to consistently follow coding rules and techniques? What are the pitfalls of not doing so? 3. Explain what a sequential access file is. What are the advantages and disadvantages of using sequential access data files? Any addition references will be greatly appreciated.

(HCI) Human Computer Interaction

23) Use drawings where necessary. (a) Explain the concept of "mental model" and say how this concept relates to Card, Moran and Newell's "Model Human Processor". (b) Explain the concept of interactivity and say how it relates to the idea of an interface, using examples and referring to the translations in Abowd and Beale's "Interaction Framework". (c) Apply the Interaction Framework to a typical scenario for using a mobile phone. Say how you think task context can affect design decisions about appropriate articulations. (d) Based on your answers to parts (a), (b) and (c) of this question and examples of your own, explain why task context and interactivity must be considered t... click for more

(HCI) Human Computer Interaction

21) Interactive computer systems can be categorized both in terms of interaction styles and interaction paradigms. This helps us to understand the problems and potential value of any interactive system design. We must also pay attention to the context of interaction, whether generic or specific designs are at stake. (a) Describe the Direct Manipulation interaction paradigms and two others, using an electronic library catalogue system as an example to show how these three paradigms relate to one another. Say which paradigm would be most suited to supporting the tasks you have identified for the library system. (b) Explain the idea of a context as it relates to HCI design. (c) ... click for more
