Modify the username.py program (see the lecture slide) to generate usernames using the user’s first initial, followed by up to 3 first letters of the user’s last name, and a number of total characters in the last name. User input can be up- or low-case. But the generated usernames contains only low-case characters and a number.

For example, if the person’s name is “Albert Einstein” à the username shall be ”aein8”

Tip: use len() function and string’s lower() method

To create the program(10 points): :

1. Create a module named h02_username2.py from the directory hw

2. Record your name, class number, and date of creation using python comment statement.

3. Write the code to implement the required tasks.

When you have completed the program, run the program and capture and paste the output below:

Q: Given the following class:

public class Student {

private String firstName;

private String lastName;

private int age;

private University university;

public Student(String firstName, String lastName, int age, University university) {

this.firstName = fisrtName;

this.lastName = lastName;

this.age = age;

this.university = university;

}

public String getFirstName(){

return firstName;

}

public String getLastName(){

return lastName;

}

public int getAge(){

return age;

}

public University getUniversity(){

return university;

}

public String toString() {

return "\nFirst name:" + firstName + "\nLast name:" + lastName + " \nAge:"+ age + "\nUniversity" + university;

}

}

a- Create the University class (data type). The class must include name, state, and the country as member variables; it must also include methods for returning and storing the name, state, and country.

b- Create client code to test the classes.

Consider a text file that you will create named “employees.txt”. The file contains data organized according to the following format:John Smith 10 15Sarah Johnson 40 12Mary Taylor 27 13Jim Stewart 25 8For instance, “John” is the first name, “Smith” is the last name, “10” is the number of hours per week, and “15” is the hourly rate.Write a program that computes the weekly salary of each employee. The program prints the first name, last name, and weekly salary of each employee in a file named “results.txt”. ‘results.txt” must be created automatically by your program. You must use a function to read/process the data from the input file and this function must have parameters. The “employees.txt” file must be opened from main and read from within your defined function. in c++

create the UML Diagram to model a Movie/TV viewing site.

Draw a complete UML class diagram which shows:

  • Classes (Only the ones listed in bold below)
  • Attributes in classes (remember to indicate privacy level, and type)
  • No need to write methods
  • Relationships between classes (has is, is a, ...)

Use a program like Lucid Cart and then upload your diagram.

Each movie has:

name, description, length, list of actors, list of prequals and sequals

Each TV Show has:

name, description, list of places that show it (netflix, hulu, pbs kids), list of actors, list of episodes

Each Episode has:

name, description, number, season, list of actors

User:

  • first and last name
  • list of movies watched, list of tv shows and espisodes within those shows watched, list of favorites

Using python

Write a program that has 3 functions, named write_to_file, read_from_file, and ask_user.

The write_to_file function should have 2 parameters, file_name and data. When called, the function will open a file with the name stored in the file_name variable, write the information stored in data, then close the file.

The read_from_file function will have 1 parameter, file_name. When called, the function will open a file with the name stored in the file_name variable, print the contents of the file, then close the file.

The ask_user function will give the user a prompt asking whether they want to read or write a file, once a selection is made the program must ask the user for the information needed to run the function (if they select write, ask for file name and data to write to the file, if the select read, ask for file name).

Below the functions, in the main part of the program, write a for loop that loops 10 times calling the ask_user function.

Must be in C#: 7. E-MAIL ADDRESS BOOK Create a Windows Forms Application with a class named PersonEntry. The PersonEntry class should have properties for a person’s name, e-mail address, and phone number. Also, create a text file that contains the names, e-mail addresses, and phone numbers for at least five people. When the application starts, it should read the data from the file and create a PersonEntry object for each person’s data. The PersonEntry objects should be added to a List, and each person’s name should be displayed in a list box on the application’s main form. When the user selects a name from the list box, a second form should appear displaying that person’s name, e-mail address, and phone number. There are additional requirements; please see Main Differences between the Textbook Instructions and This Document above.

C++ Parse text (with delimiter) read from file.

If a Text file has input formatted such as: "name,23" on every line where a comma is the delimiter, how would I separate the string "name" and integer "23" and set them to separate variables for every input of the text file? I am trying to set a name and age to an object and insert it into a vector.

#include <iostream>
#include <vector>
#include <fstream>
using namespace std;

class Student{
    public:
        string name;
        int age;
};

int main() {


    vector <Student>studentVector;
    Student s;
    string student_name;
    int student_age;
  
    ifstream myFile("file.txt");
      
    while(myFile>> student_name >> student_age){


        //s.name is assigning the entire line of unparsed text
        s.name = student_name;

       ///age is not read because input string from file is not parsed

        s.age = student_age;


        studentVector.push_back(s);
    }


    return 0;
}

1, If we want to display output from a command, such as DIR or TYPE, one screen at a time, we can use what kind of command?

> MORE

| PAGE

| MORE

>> PAGE

2, To delete a directory that contains subdirectories and/or files, we will use what command:

DEL directory name /S

MD directory name /S

RD directory name /S

RMDIR directory name

3, When we are using certain tools (e.g. WMIC, DISKPART, and NETSH) in the Interactive Mode, most of the internal Command Prompt commands, such as CLS and CD, would not work. However, which command will work?

BYE

EXIT

| MORE

START

4, When we use this command in a batch file, the user must pick from the available options because Command Prompt won't let s/he pick anything else:

CHOICE

IF ELSE

FOR

I need to write a program in python for a restaurant. The program should let the user enter a meal number, then it should display the meal name, meal price, and meal calories. Also, needs the appropriate output if the user enters an invalid meal number. I am supposed to use a dictionary, but my problem is it keeps giving me an error and telling me my menu is not defined. Not sure what I am doing wrong.


print ("Welcome to INN N OUT, what would you like to order today?")
print("------Menu------")
print("Double Double - 1")
print("Cheeseburger - 2")
print("Hamburger - 3")

def Menu():
menu = {

1 : {'name' : 'Double Double','price' : 3.45,'calories' : 670},

2 : {'name' : 'Cheeseburger','price' : 2.40,'calories' : 480},

3: {'name' : 'Hamburger','price' : 2.10,'calories': 310}}

x = int(input("Make a selection: "))

if x >= 1 and x <= 3:
print("You ordered a " + menu[x]['name'] + ". That is " + menu[x]['calories'] + ". Your total will be $" + menu[x]['price'])

else:
print("Invalid entry.")
