Create a project with a Program class and write the following two methods (headers provided) as described below:

1. A Method, public static int InputValue(int min, int max), to input an integer number that is between (inclusive) the range of a lower bound and an upper bound. The method should accept the lower bound and the upper bound as two parameters and allow users to re-enter the number if the number is not in the range or a non-numeric value was entered.
2. A Method, public static bool IsValid(string id), to check if an input string satisfies the following conditions: the string’s length is 5, the string starts with 2 uppercase characters and ends with 3 digits. For example, “AS122” is a valid string, “As123” or “AS1234” are not valid strings.

Python
Write a function str_slice(s) to slice sentence into single word by their spaces and punctuations and returns a list.
You cannot use split(), join() method for this define function

This program has to be written in assembly language using emu8086. Please choose the .EXE template. The requirements and the action is contained in the docx file.

You’ve been hired by Spacely Sprockets and they need to be able to write order information out to a file. Using all of the knowledge that we’ve gained in the last few sections on structures and files, you need to write a program that does the following:

1. Design a structure that can hold an order number (integer type data), a customer’s ID (integer type data), a sprocket type (string type data), a part quantity (integer type data) and an order total (floating point data). These will be simply stored in the structure as string data.
2. When your program is run, prompt the user to enter each of these pieces of data into the structure.
3. Once the last piece of structure data has been entered, prove the structure is working correctly by neatly printing the structure’s contents out to the screen.
4. Open a file up for writing and write the structure out to the file. Print a message out to the screen once the file has been created.
5. Clear any data in the structure out.
6. Open the file back up for reading and pull the data back into the structure.
7. Print the structure out to the screen again. If you are successful, the same data should appear twice on the screen (once from the filling\printing of the structure and the second time from reading the structure in from a file.

Here’s a sample run:

Order Number: 105

Customer ID: 405

Sprocket Type: Awesome Atomic Sprocket

Part Quantity: 3

Order Total: 105.74

Struct written to file C:\asm\test.txt

Order Number: 105

Customer ID: 405

Sprocket Type: Awesome Atomic Sprocket

Part Quantity: 3

Order Total: 105.74

Program Complete!

Hints: Think procedures! You can simplify the code and your debugging life by writing procedures. For example, a print structure routine, a save to file routine, a read from file routine, et cetera. Secondly, DO NOT code this application in a single shot – incrementally build up each piece of logic otherwise you will get lost when things don’t work right.

acos() Prototype

double acos(double x);

To find arc cosine of type int, float or long double, you can explicitly convert the type to double using cast operator.

 int x = 0;
 double result;
 result = acos(double(x));

 int x = 0;
 double result;
 result = acos(double(x));

acos() Parameter

The acos() function takes a single argument in the range of [-1, +1]. It's because the value of cosine is in the range of 1 and -1.

acos() Return Value

The acos() functions returns the value in range of [0.0, π] in radians. If the parameter passed to the acos() function is less than -1 or greater than 1, the function returns NaN (not a number).

Example 1: acos() function with different parameters

#include <stdio.h>
#include <math.h>

int main() {
    // constant PI is defined
    const double PI =  3.1415926;
    double x, result;

    x =  -0.5;
    result = acos(x);
    printf("Inverse of cos(%.2f) = %.2lf in radians\n", x, result);

    // converting radians to degree
    result = acos(x)*180/PI;
    printf("Inverse of cos(%.2f) = %.2lf in degrees\n", x, result);

    // paramter not in range
    x = 1.2;
    result = acos(x);
    printf("Inverse of cos(%.2f) = %.2lf", x, result);

    return 0;
}

Output

Inverse of cos(-0.50) = 2.09 in radians
Inverse of cos(-0.50) = 120.00 in degrees
Inverse of cos(1.20) = nan

Many dog owners see the benefit of buying natural dog food and treats. Dog Day Afternoon is a local company that creates its own dog food and treats. Their products are made locally and with natural ingredients. Sales are up and the owners of Dog Day Afternoon have decided to expand their business. Currently they are manually calculating sales. They need a computer program to help speed up the process.

The owners of Dog Day Afternoon decided to get some help. They approached the Career Center and posted numerous temporary programming positions. You are eager to get some experience as a programmer so you apply and get the job.

Your portion of the project is to create a class called DogDay that will take in the quantity and the size of the dog treat. Store these values in attributes called quantity (integer) and size (string). The class will also contain three methods. One method will determine the cost of one dog bone. Name this method DeterminePrice. The cost of the different size natural raw hide bones is as follows:

• Size A = $2.29
• Size B = $3.50
• Size C = $4.95
• Size D = $7.00
• Size E = $9.95

Store the cost of each individual dog bone in an attribute called price.

Your second method will be called DetermineTotal. This method will calculate the total cost (quantity * cost) and round this value to 2 decimal places. It will store this value in an attribute called total.

Your final method will return the total.

When creating this class start coding in VS Code or IDLE. To test your class create an object. Send in the values 6 and C. Next call your method DeterminePrice followed by DetermineTotal. Finally print the method ReturnTotal to the screen. Your code should print the following: 29.7

Database systems and Information systems

An information system performs three sets of services:

• It provides for data collection, storage, and retrieval.
• It facilitates the transformation of data into information.
• It provides the tools and conditions to manage both data and information.

Basically, a database is a fact (data) repository that serves an information system. If the database is designed poorly, one can hardly expect that the data/information transformation will be successful, nor is it reasonable to expect efficient and capable management of data and information.

The transformation of data into information is accomplished through application programs. It is impossible to produce good information from poor data; and, no matter how sophisticated the application programs are, it is impossible to use good application programs to overcome the effects of bad database design. In short: Good database design is the foundation of a successful information system.

Database design must yield a database that:

• Does not fall prey to uncontrolled data duplication, thus preventing data anomalies and the attendant lack of data integrity.
• Is efficient in its provision of data access.
• Serves the needs of the information system.

The last point deserves emphasis: even the best-designed database lacks value if it fails to meet information system objectives. In short, good database designers must pay close attention to the information system requirements.

Systems design and database design are usually tightly intertwined and are often performed in parallel. Therefore, database and systems designers must cooperate and coordinate to yield the best possible information system.  

The SDLC traces the history (life cycle) of an information system. The DBLC traces the history (life cycle) of a database system. Since we know that the database serves the information system, it is not surprising that the two life cycles conform to the same basic phases.

There are two basic approaches to database design: top‑down and bottom‑up.

Top‑down design begins by identifying the different entity types and the definition of each entity's attributes. In other words, top‑down design:

• starts by defining the required data sets and then
• defines the data elements for each of those data sets.

Bottom‑up design:

• first defines the required attributes and then
• groups the attributes to form entities.

Although the two methodologies tend to be complementary, database designers who deal with small databases with relatively few entities, attributes, and transactions tend to emphasize the bottom‑up approach. Database designers who deal with large, complex databases usually find that a primarily top‑down design approach is more appropriate.

Even if a generally top‑down approach is selected, the normalization process that revises existing table structures is (inevitably) a bottom‑up technique. E-R models constitute a top-down process even if the selection of attributes and entities may be described as bottom-up. Since both the E-R model and normalization techniques form the basis for most designs, the top‑down vs. bottom-up debate may be based on a distinction without a difference.  

Assignment
