Answer:

The program in Python is as follows:

fname = input("Enter the translation file name: ")

with open(fname) as file_in:

   lines = []

   for line in file_in:

       lines.append(line.rstrip('\n'))

myDict = {}

for i in range(len(lines)):

x = lines[i].split(":")

myDict[x[0].lower()] = x[1].lower()

print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")

word = input("Enter an English word: ")

while(True):

if not word:

 break

if word.lower() in myDict:

 print("The Spanish word is ",myDict[word.lower()])

else:  

 print("I don’t have that word in my list.")

word = input("Enter an English word: ")

Explanation:

This prompts the user for file name

fname = input("Enter the translation file name: ")

This opens the file for read operation

with open(fname) as file_in:

This creates an empty list

   lines = []

This reads through the lines of the file

   for line in file_in:

This appends each line as an element of the list

       lines.append(line.rstrip('\n'))

This creates an empty dictionaty

myDict = {}

This iterates through the list

for i in range(len(lines)):

This splits each list element by :

x = lines[i].split(":")

This populates the dictionary with the list elements

myDict[x[0].lower()] = x[1].lower()

This prints an instruction on how to use the program

print("Enter an English word to receive the Spanish translation.\nPress ENTER to quit.")

This prompts the user for an English word

word = input("Enter an English word: ")

This loop is repeated until the user presses the ENTER key

while(True):

If user presses the ENTER key

if not word:

The loop is exited

 break

If otherwise, this checks if the word exists in the dictionary

if word.lower() in myDict:

If yes, this prints the Spanish translation

 print("The Spanish word is ",myDict[word.lower()])

If otherwise,

else:

Print word does not exist

 print("I don’t have that word in my list.")

Prompt the user for another word

word = input("Enter an English word: ")

1. Add the following method to the Point class:
Pachacha [2.7K]

Answer:

Explanation:

The following code is written in Java and creates all of the methods that were requested in the question. There is no main method in any of these classes so they will have to be called from the main method and call one of the objects created method for the code to be tested. (I have tested it and it is working perfectly.)

class Point {

   private int x, y;

   public void Point(int x, int y) {

       this.x = x;

       this.y = y;

   }

   public double distance (Point other) {

      double distance = Math.sqrt(Math.pow((other.x - this.x), 2) + Math.pow((other.y - this.y), 2));

      return distance;

   }

   

   public int quadrant() {

       if (this.x > 0 && this.y > 0) {

           return 1;

       } else if (this.x < 0 && this.y > 0) {

           return 2;

       } else if (this.x < 0 && this.y < 0) {

           return 3;

       } else if (this.x > 0 && this.y < 0) {

           return 4;

       } else {

           return 0;

       }

   }

}

class Name {

   String firstName, lastName;

   char middleInitial;

   

   public String getNormalOrder() {

       String fullName = firstName + " " + middleInitial + " " + lastName;

       return fullName;

   }

   

   public String getReverseOrder() {

       String fullName = lastName + ", " + firstName + " " + middleInitial;

       return fullName;

   }

}

In a system where Round Robin is used for CPU scheduling, the following is TRUE when a process cannot finish its computation dur
masha68 [24]

Answer:

B. The process will be terminated by the operating system.

Explanation:

When Round Robin is used for CPU scheduling, a time scheduler which is a component of the operating system is used in regulating the operation. A time limit is set for each of the processes to be run.

So, when a process fails to complete running before its time elapses, the time scheduler would log it off and return it to the queue. This queue is in a circular form and gives each of the processes a chance to run its course.
