- The D-matrix notation can be used to describe the development of a program (since this is a detailed design). Here we might consider decisions about the tasks performed by subprograms (procedures, methods) as functional design decisions; the choice of the subprograms and any larger packaging units (such as classes) as constructional design decisions; and the choice of data structures as data-modeling design decisions. (Behavior doesn’t fit quite so well.) When you next write a program, keep a note of the development process and then try to describe this using the D-matrix form. (You may need to do group related actions to make this manageable.)Distinguish between objective and abstract variables in terms of their operationalization discrepancies.Compare and contrast the objective and abstract variables, as well as briefly explain the operationalization differences.
- Explain by giving an example of variable types.Compilers now give a wide range of abstract data types to choose from, but is there a single definition that covers all cases? If not, can you explain your reasoning and provide an example?What do you mean by dynamic initialization of a variable? Give an example.
- 1. Is the binding between a C variable and its memory location static (i.e., determined at compile time) for all variables, dynamic for all variables, or does it depend on the variable. 2. If it is the same for all variables, explain why. 3. If it is variable-dependant, give an example of a type of variable with each type of binding.State the difference between actual and formal parameters. Give an example each for clarification.The idea of "abstract data types" (ADTs) is vague. Do ADTs have any advantages? What role does the concept of heredity have in resolving issues?
- Define the term actual parameters.Can Object-Oriented Programming and Abstract Data Types Coexist? Object-oriented programming and abstract data types are two recent developments. Intentionally, that is. Do you believe there are instances when you just must disagree?a) what are the main problems associated with reuse of abstract data types? explain briefly. b) ıs there any slotion (s) (i.e design principles or concepts ) to these problems? again explain briefly
