C++ Code While Loops.

Ask user for file and open file.

Do priming read and make a while loop that: 1. Reads in numbers. 2. Counts how many there is. 3. Also for every 10 numbers in the file, print out the average of those 10 numbers. Ex: (If 20 numbers in the file. "With 10 numbers the average is .... and With 20 numbers the average is" and EX for a file with 5 numbers "There are 5 numbers in this file with an average of ..."

After the loop calculate and print the average of all nums in the file.

In this case study, your task is to study different search algorithms to solve the N-Queens Problem which has been presented in class. We will focus on the incremental formulation in which we add a queen to any square in the leftmost empty column that is not attacked by any other queen.

Question: Using Hill Climbing (HC) algorithms, how many steps are needed to find the solution for the 12-Queens Problem? What is it? Draw on an 12x12 table. Show your steps.

Create a class Superheros

member: Map heroMap //key = name, value = weapon (or get creative)

member: Set< String> powerSet //superpowers

*** initialize your map & set – preferably in constructor ***

/* One liner to ‘put’ the key, value pair you’re passing in.. */

Method: void putEntryInMap (String key, String value) {}

/* Another 1 liner – well maybe 2. (1) ‘get’ the value from the map with the key (2) capture that value and return it (to your testHarness) */

Method: String getEntryFromMap (String key) {}

/* Another 1/2 liner (1) ‘remove’ the value from the map with the key (2) check if you have actually removed your value from your map by printing the results of heroMap.hasKey(key) */

Method: void removeEntryFromMap (String key){}

/* For all the marbles… you need to: Get the keyset from your map. This will give you a set of all the keys in the map. With your keyset, iterate over each element in your set & in the loop ‘get’ the value for that key from your map & print it. (Note you will need to create a local Set variable in this method). */

Method void displayAllMapEntries(){}

/* add an element to your set */

Method void addToSet(String name){}

/* remove an element from your set */

Method void removeFromSet(String name){}

/* iterate over the elements in your set and print each */

Method void printSet(){}

In your testHarness:

- create a Superhero instance ( make sure your map & set are initialized in your Superhero ctor ) - invoke one of your Superhero methods to ‘put’ a few entries ( 4 or more ) in your map.

- invoke one of your Superhero methods to ‘display’ your cat entries - invoke one of your Superhero methods ‘get’ an entry

- capture the value returned in your harness & print it out. - invoke one of your Superhero methods ‘remove’ an entry - invoke one of your Superhero methods to ‘display’ each entry (do not just print the map)

- invoke one of your Superhero methods to ‘add’ a few entries into your set

Make sure you add a couple duplicate names!

- invoke one of your Superhero methods to ‘display’ your set (do not just print the set) - invoke one of your Superhero methods to ‘remove’ an entry from your set - invoke one of your Superhero methods to ‘display’ your updated set (do not just print the set)

Q1:

What strategic competitive benefits do you see in a company’s use of extranets?

Answer :

An extranet can increase the value of your organization by helping you convey and work together more viably with customers, clients, and accomplices. Especially in the business-to-business market, an extranet can give your organization an edge over the opposition and set aside you cash by smoothing out conventional business capacities and reducing overhead expenses.

Extranets accomplish a similar work as an intranet, however it additionally takes into account correspondence on the planet. An extranet permits client, sellers and providers to get to the data through the PC framework. The organizations use extranets to get strategic like:

1. Expanded efficiency: As you mechanize measures that were generally done physically, bottlenecks will vanish and your organization's profitability will increment. Basic data won't lose all sense of direction via the post office or covered in an email inbox, and occupied representatives won't miss or overlook key functions. An extranet can, for instance, screen business exercises and trigger explicit activities, for example, naturally submitting a request with a provider when your stock dips under a specific level.

2. More limited chance to advertise: In the event that your business isn't moving at "Web speed," you hazard being abandoned. An extranet can assist you with getting your items to showcase all the more rapidly by making proposition and determinations accessible to providers, and surrendering customers and accomplices to-date data on current undertakings.

3. Construct client loyalty : Extranets make business simpler for your clients. The more you make convenient, precise data accessible to your clients, the more probable it is you'll keep their business

4.Reduced stock : One of the signs of a business-to-business extranet is its effect on flexibly chain the board. By connecting your stock framework straightforwardly to a provider, you can handle arranges when the framework realizes you need them, in this manner lessening the stock you keep available and making the acquirement cycle more proficient.

Q2:

Data Modelling is the primary step in the process of database design. Compare and contrast Conceptual data model versus Physical data model. Illustrates with help of example to list down data (entities), relationship among data and constraints on data.

Data modelling is the first step in database design. It is the process of creating a data model for the data to be stored in a database. It is considered as the high level. It is also referred as the conceptual design. Data modeling helps in the visual representation of data and enforces business rules, regulatory compliances, and government policies on the data. Data Models ensure consistency in naming conventions, default values, semantics, security while ensuring quality of the data..It describes the data contained in the database, relationship between data items and the constraints on the data.

Conceptual data model

This Data Model defines WHAT the system contains. The purpose is to organize, scope and define business concepts and rules. It  is an organized view of database concepts and their relationships.. It does not have the complete data of the database. It is used to create  entities, their attributes, and relationships.

·Includes the important entities and the relationships among them.

·No attribute is specified.

·No primary key is specified.

Physical Data model

This Data Model describes HOW the system will be implemented using a specific DBMS system. The purpose is actual implementation of the database.It offers database abstraction and helps generate the schema. The physical data model also helps in visualizing database structure by replicating database column keys, constraints, indexes, triggers and other schemas.

• Specification all tables and columns.
• Foreign keys are used to identify relationships between tables.
• Denormalization may occur based on user requirements.
• Physical considerations may cause the physical data model to be quite different from the logical data model.

PYTHON WHILE Write a program that prompts for and reads the number ? of spheres to be processed. If ?≤0 your program must display an error message and terminate; otherwise it does the following for ? times:

• Write a program that prompts for and reads the number ?n of spheres to be processed. If ?≤0n≤0 your program must display an error message and terminate; otherwise it does the following for ?n times:
  • Prompts for and reads the volume of a sphere, it then displays the surface area of the sphere with that volume. Assume that each volume is in cubic centimeters.
• The program finally displays the average of the surface areas of the ?n spheres.
• Please note that
  • ?=3.14159π=3.14159.
  • volume =43??3=43πr3.
  • surface area =4??2=4πr2.
• The following are sample runs of the program.
