List five application programs you recommend, and write a sentence explaining why.

To assign the contents of one array to another, you must use ________.

iren [92.7K]

Answer:

Option c is the correct answer for the above question.

Explanation:

The array is used to holds multiple variables and the assignment operator can assign only a single variable at a time. So if a user wants to assign the whole array value into other array value then he needs to follow the loop.
The loop iteration moves on equal to the size of the array. It is because the array value moves into another array in one by one. It means the single value can move in a single time. So the moving processor from one array to another array takes n times if the first array size is n.
The above question asked about the processor to move the element from one array to another and the processor is a loop because the loop can execute a single statement into n times. So the C option is correct while the other is not because--

Option 'a' states about one assignment operator which is used for the one value only.
Option b states about the equality operator which is used to compare two values at a time.
Option d states any of these but only option c is the correct answer.
Option 'e' states none of these but option c is the correct.

Which is the most common drive letter where Windows stores most data and programs? A. B. C. E.

Effectus [21]

The most common drive letter where Windows stores most data and programs is "C".
In the beginning the computers used to have two floppy drives which were named as A and B. Later when hard drives added up to the technology, it was written as "C" because A and B were floppy drives already :)

Create an abstract Student class for Parker University. The class contains fields for student ID number, last name, and annual t

MrRa [10]

Answer:

<?php

abstract class Student {

public $Id; // field for student ID Number

public $Lastname; // field for student last name

public $Tuition; // field for annual tuition

public function __construct( $id, $lastname) { // constructor property to initialise id number and lastname

$this->Id = $id; // variable initialisation

$this->Lastname = $lastname;

}

// set Id number

public function setId($id) {

return $this->Id = $id;

}

// get id number

public function getId() {

return $this->Id;

}

// set lastname

public function setLastname($lastname) {

return $this->Lastname = $lastname;

}

// get lastname

public function getLastname() {

return $this->Lastname;

}

//the setTuition() method is abstract

abstract public function setTuition($amount);

// get Tuition fee

public function getTuition(){

return $this->Tuition;

}

// UndergraduateStudent is a subclass that inherits the properties of class Student

class UndergraduateStudent extends Student {

public function setTuition($amount) {

return $this->Tuition = $amount;

}

class GraduateStudent extends Student {

public function setTuition($amount) {

return $this->Tuition = $amount;

}

class StudentAtLarge extends Student{

public function setTuition($amount) {

return $this->Tuition = $amount;

}

// create an instance of the class

$Undergraduate = new UndergraduateStudent(1,"Anyadike");

// call all required methods

echo ' id: '.$Undergraduate->getId();

echo ' name:'.$Undergraduate->getLastname();

echo " Tution:".$Undergraduate->setTuition("$4000");

echo " ";

$GraduateStudent = new GraduateStudent(2,"Okonkwo");

echo ' id: '.$GraduateStudent->getId();

echo ' name:'.$GraduateStudent->getLastname();

echo " Tution:".$GraduateStudent->setTuition("$6000");

echo " ";

$StudentAtLarge = new StudentAtLarge(3,"Ojukwu");

echo ' id: '.$StudentAtLarge->getId();

echo ' name:'.$StudentAtLarge->getLastname();

echo " Tution:".$StudentAtLarge->setTuition("$2000");

Write a function called 'game_of_eights()' that accepts a list of numbers as an argument and then returns 'True' if two consecut

MrRa [10]

Answer:

In Python:

def main():

n = int(input("List items: "))

mylist = []

for i in range(n):

listitem = input(", ")

if listitem.isdecimal() == True:

mylist.append(int(listitem))

else:

mylist.append(listitem)

print(game_of_eights(mylist))

def game_of_eights(mylist):

retVal = "False"

intOnly = True

for i in range(len(mylist)):

if isinstance(mylist[i],int) == False:

intOnly=False

retVal = "Please, enter only integers"

if(intOnly == True):

for i in range(len(mylist)-1):

if mylist[i] == 8 and mylist[i+1]==8:

retVal = "True"

break

return retVal

if __name__ == "__main__":

main()

Explanation:

The main begins here

def main():

This gets the number of list items from the user

n = int(input("List items: "))

This declares an empty list

mylist = []

This iterates through the number of list items

for i in range(n):

This gets input for each list item, separated by comma

listitem = input(", ")

Checks for string and integer input before inserting item into the list

if listitem.isdecimal() == True:

mylist.append(int(listitem))

else:

mylist.append(listitem)

This calls the game_of_eights function

print(game_of_eights(mylist))

The game_of_eights function begins here

def game_of_eights(mylist):

This initializes the return value to false

retVal = "False"

This initializes a boolean variable to true

intOnly = True

This following iteration checks if the list contains integers only

for i in range(len(mylist)):

If no, the boolean variable is set to false and the return value is set to "integer only"

if isinstance(mylist[i],int) == False:

intOnly=False

retVal = "Please, enter only integers"

This is executed if the integer contains only integers

if(intOnly == True):

Iterate through the list

for i in range(len(mylist)-1):

If consecutive 8's is found, update the return variable to True

if mylist[i] == 8 and mylist[i+1]==8:

retVal = "True"

break

This returns either True, False or Integer only

return retVal

This calls the main method

if __name__ == "__main__":

main()
