Programming & Computer Science Answers

Polly Pipe is a water sports provider and installer based in Braintree, England. They need you to design and implement a database that meets the data requirements. These necessities are defined in this scenario and below are samples of the paper records that the Polly Pipe preserves.

Polly Pipe is focused in placing aquariums at business customers. Customers can request several installations, but each installation is tailor-made for a specific customer. Facilities are classified by type. One or more employees are assigned to each facility. Because these facilities are often very large, they can include carpenters and masons as well as water installers. The facilities use equipment such as aquariums, air pumps and thermostats. There can be multiple computers in a facility.

Below are examples of paper records that Polly Pipe currently maintains.

Create an ERD for this.

Hollow Inverted Half Pyramid - 2

Given the number of rows N, write a program to print the hallow inverted half pyramid pattern similar to the pattern shown below.

1 2 3 4 5

1 4

1 3

1 2

1

Input

The input will be a single line containing a positive integer (N).

Output

The output should be N rows containing the numbers in the hollow inverted half pyramid pattern.

Note: There is a space after each number.

Q.1.1 Identify a suitable network scenario/ case that can be used to explain and discuss the relationship of concepts in the exhibit. Ensure that you provide details of the following aspects of the scenario:  • Description of the scenario;  • Why the scenario is considered a network system.  

Q.1.2 As part of the requirements analysis, list the requirements for each component or related area presented in the exhibit. Include the following components or network areas:  • Network systems and related network protocols;  • Network systems and related network traffic;  • Network systems and related embedded systems.  (15)        

Q.1.3 Using Q.1.1 and Q.1.2 above, discuss the relationship between the concepts as presented in the exhibit. In particular, explain the importance of understanding these relationships in network systems design. 

implement a list data structure including following operations using array adt .

get() update() length() back() next() start() end() remove() add() .

Note: implement above operations only using pointers without using any indexes of arrays.

As part of the requirements analysis, list the requirements for each component or related area presented in the exhibit. Include the following components or network areas:

• Network systems and related network protocols;

• Network systems and related network traffic;

• Network systems and related embedded systems

Create an algorithm, pseudocode and flowchart. Phoenix store wants a daily sales transaction. Computer will compute and display total sales per transaction and discount amount given to senior citizen, person with disabilities and with membership card. This store only sells the following books. English 1, English 2, English 3, Physics 1, Physics 2, Physics 3, Introduction to Computer Science, Python, WPF, Web Development, Psychology, Chemistry 2, Our Daily Bread. Price are not permanent and depends based on entry of staff. The books not sold per transaction, corresponding prices equivalent to zero, books sold per transaction and prices of each book vary to entry of the staff. Get the total sales and discount amount.

Total sales= sum of the prices each book sells by bookstore

Discount for Senior Citizen= 30% of total sales per transaction

Discount for PWD=20% of total sales per transaction

Discount for Members=15% of total sales per transaction

Note: no discounts will be given to regular customers

Exemplify the developer myths with suitable scenario

1.      Dynamic loading of functions  

a.      Your main program and interpret function should be compiled separately. In the file ~/.bash_profile export the environment variable LD_LIBRARY_PATH      export  LD_LIBRARY_PATH=.  

This will take effect the next time you log in.  To make this effective in your current session you would have to export the variable manually.  

i.        replace the default config file with your 2^nd config file and send a SIGHUP signal to your program. Verify that your program is now running the implemented functions. 

ii.       Include code that loads the functions (see example pluginShell.c) and modify it so that it also loads help.
