Write a programmer defined function that compares the ASCII sum of two strings. To compute the ASCII sum, you need to compute the ASCII value of each character of the string and sum them up. You will thus need to calculate two sums, one for each string. Then, return true if the first string has a larger ASCII sum compared to the second string, otherwise return false. In your main function, prompt the user to enter two strings with a suitable message and provide the strings to the function during function call. The user may enter multiple words for either string. Then, use the Boolean data returned by the function to inform which string has the higher ASCII sum.

Answers

Answer:

The program in Python is as follows:

def ASCIIsum(str1,str2):

   asciisum1 = 0;    asciisum2 = 0

   for chr in str1:

       asciisum1 += (ord(chr) - 96)

   for chr in str2:

       asciisum2 += (ord(chr) - 96)

   if asciisum1 > asciisum2:

       return True

   else:

       return False

str1 = input("Enter first string: ")

str2 = input("Enter second string: ")

if ASCIIsum(str1,str2) == True:

   print(str1,"has a higher ASCII value")

else:

   print(str2,"has a higher ASCII value")

Explanation:

This defines the function

def ASCIIsum(str1,str2):

This initializes the ascii sum of both strings to 0

   asciisum1 = 0;    asciisum2 = 0

This iterates through the characters of str1 and add up the ascii values of each character

   for chr in str1:

       asciisum1 += (ord(chr) - 96)

This iterates through the characters of str2 and add up the ascii values of each character

   for chr in str2:

       asciisum2 += (ord(chr) - 96)

This returns true if the first string has a greater ascii value

   if asciisum1 > asciisum2:

       return True

This returns false if the second string has a greater ascii value

   else:

       return False

The main begins here

This gets input for first string

str1 = input("Enter first string: ")

This gets input for second string

str2 = input("Enter second string: ")

If the returned value is True

if ASCIIsum(str1,str2) == True:

Then str1 has a greater ascii value

   print(str1,"has a higher ASCII value")

If otherwise

else:

Then str2 has a greater ascii value

   print(str2,"has a higher ASCII value")

Suppose during a TCP connection between A and B, B acting as a TCP receiver, sometimes discards segments received out of sequence, but sometimes buffers them. Would the data sent by A still be delivered reliably and in-sequence at B? Explain why.

Answers

Answer:

Yes

Explanation:

We known that TCP is the connection [tex]\text{oriented}[/tex] protocol. So the TCP expects for the target host to acknowledge or to check that the [tex]\text{communication}[/tex] session has been established or not.

Also the End stations that is running reliable protocols will be working together in order to verify transmission of data so as to ensure the accuracy and the integrity of the data. Hence it is reliable and so the data can be sent A will still be delivered reliably and it is in-sequence at B.

Write a program that will read two floating point numbers (the first read into a variable called first and the second read into a variable called second) and then calls the function swap with the actual parameters first and second. The swap function having formal parameters number1 and number2 should swap the value of the two variables.
Sample Run:
Enter the first number
Then hit enter
80
Enter the second number
Then hit enter
70
You input the numbers as 80 and 70.
After swapping, the first number has the value of 70 which was the value of the
second number
The second number has the value of 80 which was the value of the first number

Answers

Answer:

The program in Python is as follows:

def swap(number1,number2):

   number1,number2 = number2,number1

   return number1, number2

   

first = int(input("First: "))

second = int(input("Second: "))

print("You input the numbers as ",first,"and",second)

first,second= swap(first,second)

print("After swapping\nFirst: ",first,"\nSecond:",second)

Explanation:

This defines the function

def swap(number1,number2):

This swaps the numbers

   number1,number2 = number2,number1

This returns the swapped numbers

   return number1, number2

The main begins here

This gets input for first    

first = int(input("First: "))

This gets input for second

second = int(input("Second: "))

Print the number before swapping

print("You input the numbers as ",first,"and",second)

This swaps the numbers

first,second= swap(first,second)

This prints the numbers after swapping

print("After swapping\nFirst: ",first,"\nSecond:",second)

It returns 1 if it is valid, and returns 0 if it is not valid.For example, the following expressions are valid: [ A * {B (C D)}] and [{()()}]The following expressions are invalid: [ A * {B (C D})], [ { ( ] ) ( ) }

Answers

Answer:

Explanation:

The following code is written in Java. It uses for loops to loop through the array of characters, and uses IF statements to check if the symbols in the expression are balanced. If so it returns true, otherwise it breaks the function and returns false. Two test cases have been provided in the main method and the output can be seen in the attached image below.

Write a class called Student that has two private data members - the student's name and grade. It should have an init method that takes two values and uses them to initialize the data members. It should have a get_grade method.

Answers

Answer:

Explanation:

The following class is written in Python as it is the language that uses the init method. The class contains all of the data members as requested as well as the init and get_grade method. It also contains a setter method for both data variables and a get_name method as well. The code can also be seen in the attached image below.

class Student:

   _name = ""

   _grade = ""

   def __init__(self, name, grade):

       self._name = name

       self._grade = grade

   def set_name(self, name):

       self._name = name

   def set_grade(self, grade):

       self._grade = grade

   def get_name(self):

       return self._name

   def get_grade(self):

Write a method swapArrayEnds() that swaps the first and last elements of its array parameter. Ex: sortArray

Answers

I understand you want a function that swaps the first and last element of an array so that the first element takes the last one's value and vice versa.

Answer and Explanation:

Using Javascript programming language:

function swapArrayEnds(sortArray){

var newArray= sortArray.values();

var firstElement=newArray[0];

newArray[0]=newArray[newArray.length-1];

newArray[newArray.length-1]=firstElement;

return newArray;

}

var exampleArray=[2, 5, 6, 8];

swapArrayEnds(exampleArray);

In the function above we defined the swapArray function by passing an array parameter that is sorted by swapping its first and last element. We first get the elements of the arrayvusing the array values method. We then store the value of the first element in the variable firstElement so that we are able to retain the value and then switch the values of the first element before using the firstElement to switch value of the last element. We then return newArray and call the function.

Unfortunately, you did not provide any context or background about the situation of Sally and the problem with her slides. We do not know it, just you.

However, trying to be of help, we can comment on the following general terms.

When someone does not meet professional expectations, this means that this individual did not prepare her presentation, lacked technical skills, did not included proper sources, or missed the proper visual aids to make the presentation more attractive and dynamic.

What Sally can improve about her slides is the following.

She can design a better structure for the presentation to have more congruence.

Sally has to clearly establish the goal or goals for her presentation.

She has to add many visuals instead of plain text. This way she can better capture the interest of her audience.

If she can use more vivid colors instead of pale or dark ones, that would be best.

No paragraphs unless necessary. She better uses bullet points.

Here the answer is given as follows,

Explanation:

Operating Platform:-  

In terms of platforms, there are differences between, mobile games and pc games within the way it's used, the operator, the most event play, the sport design, and even the way the sport work. we all know that each one the games on console platforms, PC and mobile, have their own characteristic which has advantages and disadvantages All platforms compete to win the rating for the sake of their platform continuity.  

Operating system architectures:-  

Arm: not powerful compared to x86 has many limitations maximum possibility on arm arch is mobile gaming.  

X86: very powerful, huge development so easy to develop games on platforms like unity and unreal, huge hardware compatibility and support  

Storage management:-  

On the storage side, we've few choices where HDD is slow and too old even a replacement console using SSD. so SSD is the suggested choice. But wait SSD have also many options like SATA and nvme.    

Memory management:-  

As recommended windows, Each process on 32-bit Microsoft Windows has its own virtual address space that permits addressing up to 4 gigabytes of memory. Each process on 64-bit Windows features a virtual address space of 8 terabytes. All threads of a process can access its virtual address space. However, threads cannot access memory that belongs to a different process.  

Distributed systems and networks:-  

Network-based multi-user interaction systems like network games typically include a database shared among the players that are physically distributed and interact with each other over the network. Currently, network game developers need to implement the shared database and inter-player communications from scratch.  

Security:-  

As security side every game, there's an excellent risk that, within the heat of the instant, data are going to be transmitted that you simply better keep to yourself. There are many threats to your IT.  

Define on the whole data protection matters when developing games software may cause significant competitive advantages. Data controllers are obliged under the GDPR to attenuate data collection and processing, using, as an example , anonymization or pseudonymization of private data where feasible.

Given main(), complete the Car class (in file Car.java) with methods to set and get the purchase price of a car (setPurchasePrice(), getPurchasePrice()), and to output the car's information (printInfo()).
Ex: If the input is:
2011
18000
2018
where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, the output is:
Car's information:
Model year: 2011
Purchase price: 18000
Current value: 5770
Note: printInfo() should use three spaces for indentation.

Answers

Answer and Explanation:

public class Main {

int Carmodel;

int Purchaseprice;

int Currentyear;

Public void setPurchasePrice(int Purchaseprice){

this.Purchaseprice=Purchaseprice;

}

Public void getPurchasePrice(){

return Purchaseprice;

}

static void printInfo(int Carmodel int Currentyear ){

this.Carmodel=Carmodel;

this.Currentyear=Currentyear;

System.out.println(getPurchasePrice() Carmodel Currentyear);

}

}

The above java program defines a class that has three methods, a get method that returns purchase price of the object, a set method that sets purchase price of the object, and a print method that print out the information about the car object(model, year, price). The print method also takes arguments and assigns values of the arguments/parameters to the object, then prints all.

Or we use the do...while loop

Var positiveInt= window.prompt("insert positive integer");

do{

Var positiveInt= window.prompt("insert positive integer");
