Prototyping and its type

Software prototyping is the activity of creating prototypes of software applications,
i.e., incomplete versions of the software program being developed. It is an activity
that can occur in software development

Types of prototyping

Throwaway prototyping

Also called close-ended prototyping. Throwaway or Rapid Prototyping refers to the
creation of a model that will eventually be discarded rather than becoming part of the
final delivered software. After preliminary requirements gathering is accomplished, a
simple working model of the system is constructed to visually show the users what
their requirements may look like when they are implemented into a finished system.

Evolutionary prototyping

Evolutionary Prototyping (also known as breadboard prototyping) is quite different
from Throwaway Prototyping. The main goal when using Evolutionary Prototyping is
to build a very robust prototype in a structured manner and constantly refine it. The
reason for this is that the Evolutionary prototype, when built, forms the heart of the
new system, and the improvements and further requirements will be built.

Incremental prototyping

The final product is built as separate prototypes. At the end the separate prototypes
are merged in an overall design. By the help of incremental prototyping we can
reduce the time gap between user and software developer.

Extreme prototyping

Extreme Prototyping as a development process is used especially for developing
web applications. Basically, it breaks down web development into three phases,

each one based on the preceding one.

Artificial Intelligence 1.    What is AI technique? Artificial  Intelligence (AI)  is  the study  of  how  to make computers do things which, at  the moment, people do better. It is a method that exploits knowledge that should be represented in such a way that: ·    The knowledge captures generalizations. ·    It can be understood by people who must provide it. ·    It can be easily modified to correct errors and to reflect changes. ·    It can be used in situations even if it is not accurate and complete. ·    It helps to narrow the range of possibilities that is has to be considered. 2.    What are the steps to be considered to solve a problem? To solve a particular problem, the following steps are taken into account, ·    Define the problem precisely. ·    Analyze the problem. ·    Isolate and represent the task knowledge that is necessary to solve a problem. ·    Choose the best problem-solving techniques and apply it to a particular problem.

The taxonomy of CASE Tools

CASE Tool Taxonomy CASE tools can be classified by · by function, · by user type (e.g. manager, tester), or · by stage in SE process (e.g. requirements, test) The following taxonomy is classified by function. Business Information Tools model business information flow. The tools represent business data object and model their flow. Network tools could be modified to yield the same functionality. Process Management Tools model processes. You have to understand the process in order to model it. The tools help you capture process. This is a key component of TQI. Project Planning Tools help plan and schedule projects. Examples are PERT and CPM. Finding parallelismand eliminating bottlenecks assist in streamlining projects. Risk Analysis Tools helps build a risk table from the schedule outlining the risk each component of the production process and categorizing the risks as catastrophic, critical, marginal, or negligible. A cost is associated with eac

Zoho Second round - adding a digit to all the digits of a number

Adding a digit to all the digits of a number eg digit=4, number = 2875, o/p= 612119 C Program: #include<stdio.h> #include<conio.h> #include<string.h> int main() {     int t,n,i=0;     char num[100];     printf("Enter the digit: ");     scanf("%d",&n);     printf("Enter the number: ");     scanf("%s",num);     printf("o/p ");     for(i=0;i<strlen(num);i++)     {     printf("%d",num[i]-'0'+n);     }  getch();  return 0; }
