Software Engineering

Assuming you understand what Pair-wise programming is, we can in general say that it is advantageous because the overall logic of the code written, the idea behind using certain constructs in the code, etc. are known to different people rather than a single head. Since, two or more heads is obviously better than one, we see that Pair-wise programming is certainly advantageous. But, the flip-side is say you are stuck in a situation in the code-development and one fine afternoon you get a flash but you cannot code because your partner is not there. Also, increased costs is another disadvantage. These are the basic points and I can assure you that there are several subtleties involved.

In RAD, the project is divided into modules and each module is alloted to different team. Each team work on the module in a sequential manner.

A university has a large number of courses in catalog.Attributes of COURSE include Course_Number(identifier),Course_Name and Units.Each course may have one or more course as prerequisties or may have no prerequisties.Similarly,a particular course may be a prerequisties for any number of courses or may not be prerequities for any other course.

It means you must meet the requirements for entrance to the major. Its not open to all students but only those who qualify. You will usually find this in the health related majors.

Mental models are the theories people build to understand the causal behavior of systems. These are often partial, unstable and subject to change. They may be internally inconsistent. They may be superstitious and based on incorrect interpretation of evidence. They are important, as errors can occur if the user's model is incorrect or if the designer has a different model than the user. One way of minimizing problems is supporting conventions - another is to make the correct model explicit.

There are several ways to do this in C:

// nums to swap

int a = 5;

int b = 10;

// using a temporary variable - often the fastest method

int temp;

temp = a;

a = b;

b = temp;

// using addition (no additional storage needed)

a = a + b;

b = a - b;

a = a - b;

// using xor (no additional storage needed)

a = a^b;

b = a^b;

a = a^b;

// using only one line (no additional storage needed) // note, this appears to be a compiler-dependent way to swap variables

a = a + b - (b=a);

1) Identify client requirements

2) Identify system requirements

3) Create an overall design

4) Create a detailed design

5) Develop product

6) Test product

The Prototyping Model is a frameworks improvement technique (SDM) in which a model (an early guess of a last framework or item) is assembled, tried, and after that revised as vital until the point when a worthy model is at last accomplished from which the total framework or item would now be able to be created. This model works best in situations where not the majority of the undertaking prerequisites are known in detail early. It is an iterative, experimentation process that happens between the engineers and the clients.

45 in binary is 101101, so you need at least 6 bits to represent 45 characters.

a persitent object is the one that is stored permanently on the disk......whereas a transient object is stored temporarily on the ram....

For a physical Data Flow Diagram you explore into the logical DFD. for example, if you have a data flow arrow declared as "customer information" now the physical DFD would include in that data flow arrow "customer information = customer_name + customer_address". something along these lines

Physical DFD shows how various functions are performed and who does them but Logical DFD strips away all physical constraints but does not restrict physical happenings from taking place.

When you customer has a legitimate need bit is clueless about details/ requirements then develop a prototype as a first step.

Not unless we know what type/s of cultural program/s you are referrng to.

The development approack followed is "quick and dirty",the focus is on quicker development rather than on the quality.

Yes, this program is the same as flowchart, pseudo code.

another option is to use Note Tab Light and the Pseudo code library.

No. Pseudocode is, as the name suggests, not real code. Pseudocode is an abstract concept that is often used in literature to highlight a principle or solution without focussing on the syntax details of a specific computer programming language.

For example, one language might make assignments with the '=' operator, another one might require the use of ':=' or '<-'. Other languages might even control assignments in a totally different way, for example by implication such as in stack-oriented programming languages.

Some languages might provide an "else if" construct to further diversify the else-branch of an if-clause, while others might use the "elif" keyword, or a different construct.

These are syntax details of programming languages, and are often irrelevant when discussing more abstract concepts in a language-independent way. Pseudocode aims to provide an intuitive description. The fact that the reader knows this to be pseudocode means that nobody ought to argue about the position of a semicolon or the use of single versus double quotes; you'd know this is not the real code in any specific language, but probably close for easy implementation at least with functional languages.

For example, when describing a general-purpose algorithm to sort items in a sequential list, pseudocode might say

if a > b then

swap a, b

The reader is required to transcode pseudocode into the specific programming language intented (C, Basic, Pascal, Perl, whatever).

Pseudocode is often used when describing generic algorithms, such as sort algorithms.
