// This pseudocode segment is intended to compute and display

1 answer:

3 0

The pseudocode to calculate the average of the test scores until the user enters a negative input serves as a prototype of the actual program

<h3>The errors in the pseudocode</h3>

The errors in the pseudocode include:

Inclusion of unusable segments
Incorrect variables
Incorrect loops

<h3>The correct pseudocode</h3>

The correct pseudocode where all errors are corrected and the unusable segments are removed is as follows:

start

Declarations

num test1

num test2

num test3

num average

output "Enter score for test 1 or a negative number to quit"

input test1

while test1 >= 0

output "Enter score for test 2"

input test2

output "Enter score for test 3"

input test3

average = (test1 + test2 + test3) / 3

output "Average is ", average

output "Enter score for test 1 or a negative number to quit"

input test1

endwhile

output "End of program"

stop

Answer:

import java.util.Scanner;

public class ArraysKeyValue {

public static void main (String [] args) {

final int SIZE_LIST = 4;

int[] keysList = new int[SIZE_LIST];

int[] itemsList = new int[SIZE_LIST];

int i;

keysList[0] = 13;

keysList[1] = 47;

keysList[2] = 71;

keysList[3] = 59;

itemsList[0] = 12;

itemsList[1] = 36;

itemsList[2] = 72;

itemsList[3] = 54;

/* Your solution goes here */

for ( i = 0; i < SIZE_LIST; i++){

if (keysList[i]>50){

System.out.println(itemsList[i] + " "); } }

System.out.println("");

}

Explanation:

I will explain the whole program flow.

There are two arrays here

keysList and itemsList

The first list (keysList) contains the following elements:

13 element at first position of the array (0th index)

47 element at second position of the array (1st index)

71 element at third position of the array (2nd index)

59 element at fourth position of the array (3rd index)

The other list (itemsList) contains the following elements:

12 element at first position of the array (0th index)

36 element at second position of the array (1st index)

72 element at third position of the array (2nd index)

54 element at fourth position of the array (3rd index)

The size of the array elements is fixed which is 4 and is stored in the variable SIZE_LIST.

Then the loop starts. The loop contains a variable i which is initialized to 0. First it checks if the value of i is less than the size of the list. It is true as SIZE_LIST=4 and i=0.
So the program control enters the body of the loop.
In first iteration, IF condition checks if the i-th element of the keysList is greater than 50. As i=0 So the element at 0th index of the keysList is 13 which is not greater than 50 so the body of IF statement will not execute as the condition evaluates to false. The value of i increments by 1 so now i becomes 1.
In next iteration loop again checks if the value of i is less than the size of the list which is true again so the body of the loop executes.

IF condition checks if the i-th element of the keysList is greater than 50. As i=1 So the element at 1st index of the keysList is 47 which is not greater than 50 so the body of IF statement will not execute as the condition evaluates to false. The value of i is incremented by 1 so now i becomes 2.

In next iteration loop again checks if the value of i is less than the size of the list which is true again as i= 2 which is less than SIZE_LIST so the body of the loop executes.

IF condition checks if the i-th element of the keysList is greater than 50. As i=2 So the element at 2nd index of the keysList is 71 which is greater than 50 so the body of IF statement is executed as the condition evaluates to true. So in the body of the IF statement there is a print statement which prints the i-th element of the itemsList. As i = 2 so the value at the index 2 of the itemsList is displayed in the output which is 72. Next value of i is incremented by 1 so now i becomes 3.

In next iteration loop again checks if the value of i is less than the size of the list which is true again as i= 3 which is less than SIZE_LIST so the body of the loop executes.

IF condition checks if the i-th element of the keysList is greater than 50. As i=3 So the element at 3rd index of the keysList is 59 which is greater than 50 so the body of IF statement is executed as the condition evaluates to true. So in the body of the IF statement there is a print statement which prints the i-th element of the itemsList. As i = 3 so the value at the index 3 of the itemsList is displayed in the output which is 54. Next value of i is incremented by 1 so now i becomes 4.

In next iteration loop again checks if the value of i is less than the size of the list which is now false as i=4 which is equal to the SIZE_LIST= 4. So the loop breaks.
So the output of the above program is:

Differences between windows xp and windows vista

krek1111 [17]

Well since Windows XP runs on Windows 2000 technology,it would be "slow".Also that Windows XP had MSN,which expired 15 years ago,but the good thing about Windows XP is that it can connect to the internet via WiFi without the computers hardware used for WiFi(PC only).Also that Windows XP has a logo on the start-up screen.Windows Vista on the other hand, doesn't have a logo on the start-up screen,but shows a Windows Vista animated logo atfer the start-up screen.Also that some people named Windows Vista "The first Windows 7".But somewhat,Windows Vista ran faster than Windows XP at starting up.Windows Vista was old,but it sold better than Windows XP.

Write a program whose input is two integers. Output the first integer and subsequent increments of 5 as long as the value is les

adell [148]

Answer:

Following are the code to the given question:

For code 1:

start = int(input())#defining a start variable that takes input from the user end

end = int(input())#defining a end variable that takes input from the user end

if start > end:#use if that checks start value greater than end value

print("Second integer can't be less than the first.")#print message

else:#defining else block

while start <= end:#defining a while loop that checks start value less than equal to end value

print(start, end=' ')#print input value

start += 5#incrementing the start value by 5

print()#use print for space

For code 2:

while True:#defining a while loop that runs when its true

data = input()#defining a data variable that inputs values

if data == 'Done' or data == 'done' or data == 'd':#defining if block that checks data value

break#use break keyword

rev = ''#defining a string variable rev

for ch in data:#defining a for loop that adds value in string variable

rev = ch + rev#adding value in rev variable

print(rev)#print rev value

Explanation:

In the first code two-variable "first and end" is declared that takes input from the user end. After inputting the value if a block is used that checks start value greater than end value and use the print method that prints message.

In the else block a while loop is declared that checks start value less than equal to end value and inside the loop it prints input value and increments the start value by 5.

In the second code, a while loop runs when it's true and defines a data variable that inputs values. In the if block is used that checks data value and use break keyword.

In the next step, "rev" as a string variable is declared that uses the for loop that adds value in its variable and prints its values.
