Discuss the scaled index addressing mode and comments on the following instructions?

a) MOV BX, [CX+5AX]
b) MOV [DX5DI+30H], CX

Answers

Answer 1

Memory will also be accessible in Scaled index addressing mode using a 32-bit base & indexing register.The instruction's first parameter will be the base register, and the instruction's second parameter will be the index register. The index register is multiplied by a scaling factor before the program is fetched.

For option a:

The baseline register is [tex]\bold{BX}[/tex], while the index register is [tex]\bold{CX+5*AX}[/tex].

The multiplier for Accumulator [tex]\bold{AX }[/tex] will be 5.[tex]\bold{CX }[/tex] will be multiplied with this value.[tex]\bold{CX+5*AX}[/tex] will contain a memory address.The value at position [tex]\bold{CX+5*AX}[/tex] is accessed by [tex]\bold{[{CX+5*AX} ]}[/tex].The value retrieved from the address [tex][\bold{CX+5*AX}][/tex] is moved into Base register BX by the MOV instruction.

For option b:

Its index register is [tex]\bold{CX }[/tex], whereas the base register is [tex]\bold{DX5*DI+30H}[/tex].

[tex]\bold{CX}[/tex] has a number, that is copied to a computed place below.After multiplying [tex]\bold{DI}[/tex] by [tex]\bold{5, DX}[/tex] will be multiplied by this [tex]\bold{5*DI}[/tex].To the aforementioned multiplied value,[tex]\bold{ 30H}[/tex] will be added.[tex]\bold{[DX5*DI+30H]}[/tex] is a value located at location [tex]\bold{DX5*DI+30H}[/tex]. [tex]\bold{DX5*DI+30H }[/tex] is a memory address number.As a result, the value of [tex]\bold{CX}[/tex] will be copied to the [tex]\bold{ [DX5*DI+30H] }[/tex]location.

Polymorphism with Stores - PYTHON
The goal of this program is to create classes that represent to a certain degree different types of stores in real life and the information tracked and services provided by these stores. In order to accomplish this the following required classes have to be created:
I. Create a file called store.py which contains an abstract class called Store which is made up of the following:
Attributes/Properties
o Store name
o Store address
Store availability/status (open or closed)
o Sales tax percentage Functions/Functionality
o Constructor which provides the ability to pass and set the values for the various attributes
Getter and setters for all the attributes mentioned above is_store_open should return True if the store is open and False if the store is closed
Abstract function called: calculate_total_sales_tax
o Abstract function called calculate_total_sales
II. Create a file called restaurant.py which contains a class called Restaurant which is type of Store. It should possess all the attributes and functions present in the Store class without having to re-implement those in the Restaurant class.
The Restaurant class is made up of the following:
Attributes/Properties
o Total number of people served Max occupancy
o Current occupancy o Price per person Functions/Functionality
o Constructor which provides the ability to pass and set the values for the various attributes
seat_patrons should do the following: Take the number of people to be seated as input
Update the values of the appropriate attributes
If number of people to be seated does not exceed or equals the max occupancy
Print "Welcome to [replace with name of restaurant]"
• Return True If number of people to be seated exceeds the max occupancy
Print "We are at capacity, we appreciate your patience"
Return False
serve_patrons which should do the following:
Take the number of people to serve as input
Update the values of the appropriate attributes
Return the number of people being served currently
o checkout_patrons (this is when the patrons are ready to leave the restaurant) which should do the following:
Take the number of people leaving as input
Update the values of the appropriate attributes
Return the current occupancy of the restaurant
o Create a getter and setter for the attribute: Price per person
III. Create a file called grocery_store.py which contains a class called GroceryStore which is type of Store.
It should possess all the attributes and functions present in the Store class without having to re-implement those in the GroceryStore class.
The GroceryStore class is made up of the following:
Attributes/Properties
o Total revenue
Grocery store type (independent or chain)
Functions/Functionality
o Constructor which provides the ability to pass and set the values for the various attributes
sell_item which should do the following:
Takes the quantity and price of an item as input
Update the values of the appropriate attributes
Return the total revenue of the grocery store
o Create a getter and setter for the attribute: Grocery Store type
IV. Create a file called shopping.py which will make use of the above mentioned Restaurant and GroceryStore classes and call their various functions to simulate the actions which take place in real life restaurants and grocery stores in order to test your code.
Reminder: Do not forget to implement the two abstract functions specified in the Store class within each of the classes mentioned above

Polymorphism is used in Python for a variety of purposes, most notably Duck Typing, Operator and Method overloading, and Method overriding, just like it is in other programming languages like Java and C++.

What role of Polymorphism is used in different program?

The + operator is used to execute arithmetic addition operations on integer data types. As a result, the procedure above produces 3. The + operator is also used to execute concatenation for string data types. The output of the aforementioned application is Python Programming.

The opposite of uniformity, polymorphism, is defined as having “various forms.” Overloading and overriding are two different approaches to implement this polymorphism.

Therefore,`Three types of polymorphism exist in object-oriented programming languages: subtype polymorphism, parametric polymorphism, and ad-hoc polymorphism.
