Write a program that read the input from user and convert it to binary and hex in C language.

Use the enum keyword or a C++ class to create a new type Boolean with the two values F and T defined. Use the C++ class/struct keyword and an array to create a list of pairs that cover all possible combinations of the 2 Boolean constants you defined.

I am having trouble with printing the linked list from user input. Can someone tell me what I am doing wrong.

#include <iostream>
using namespace std;
struct node
{
   int info;
   node*link;
   node*current;
   node*prev;
   node * head;
   node * last;
}
;

void Insert(node*&head,node*&last,int n);
int SplitList(node*&head);
void print(node*&head);
int main()
{
   int num;
   node*h;
   node*l;
   cout << "Enter numbers ending with -999" << endl;
   cin >> num;
   Insert(h, l, num);
   print(h);
}

void Insert(node *&head,node*&last,int n)
{
   int count = 0;
   if (head == NULL)
   {
       head = new node;
       head->info = n;
       head->link = NULL;
       last = head;

   node *current; //pointer to traverse the list
   current = head; //set current so that it points to
                   //the first node

In java, write a program that asks the user to enter a character. Then pass the character to the following methods.

1. isVowel() – returns true if the character is a vowel
2. isConsonant() – returns true if the character is a consonant
3. changeCase() – if the character is lower case then change it to upper case and if the character is in upper case then change it to lower case. (return type: char)

Example output is given below:

Enter a character

a

a is a vowel

a is not a consonant

a is equivalent to A

test case: e, E, d, D

Note: Java represents character using Unicode encoding and ‘A’ to ‘Z’ is represented by numbers 65 to 90 and ‘a’ to ‘z’ is represented by numbers 97 to 122. So to convert ‘A’ to ‘a’ you need to add (97-65) to A and then cast it to Character type since the addition will change its type to integer.

You can use the following code to read a character from console. When you call charAt(i) method for any String it returns the character at index i. The index of first character is 0, the index of second character is 1 and so on.

Scanner input = new Scanner(System.in);

char ch =input.next().charAt(0);

Imagine you are responsible for the performance improvement of an old computer system. Your boss told you that since a large budget for the new fiscal year has been approved and covers expenses with hardware upgrade you can just create a cluster computer with a large number of parallel processing units managed by some cluster operating system line MS-Windows Server 2019. You will not be able to make any changes to the software. Please, provide your recommendations for your boss regarding performance improvement by increasing parallel processing.

Your objective is to write a well-documented simple program using classes, a loop, and nested ifs to simulate an ATM using JAVA.

1. Create an ATM class with class variables name, pin, and balance, a constructor with parameters to assign values to the three instance variables, methods to get the name, pin, and balance, and methods to handle validated deposits and withdrawals ( deposit and withdrawal amounts cannot be negative, and withdrawal amount must not be greater than the existing balance).

2. In the ATMTest class, read the names, 4 digit pin numbers, and account balances of two customers into two instances of the ATM class. Display the two customers names, pins, and balances formatted.

3. Now that you have all your customers’ information start your ATM to accomplish the following within an infinite loop,

a). Display a welcome screen with your bank’s information and prompt for and read the customer entered pin.

b). Use a nested if to match the entered pin with one of the two customers’ pins. If the entered pin number matches that of one of the customers, then:

i. Welcome the customer by name and display the balance.

ii. Display option to 1. DEPOSIT, 2. WITHDRAW or 3. EXIT.

iii. If option 1 is selected, then use the instance deposit method to prompt for deposit amount, read, and add a valid deposit amount to the customer’s balance

iv. If option 2 is selected, then use the instance withdrawal method to subtract a valid withdrawal amount from the customers balance

v. If option 3 is selected, go to step a.

4. Should the entered pin number not match either of the two customers, notify the customer that the entered pin is not valid and go to step a.

5. Selection of the EXIT option must display welcome/login screen (step a).

6. Should an incorrect option be entered, notify the user and display the original welcome/login screen (step a).

I need the program to continue asking the user for a positive value and NOT skip to the value for store 2 if a negative value is entered. This is the code so far: Thanks

public static void main(String[] args) {
  

       Scanner input = new Scanner(System.in);//scanner
       int Store [] = new int[5];//array for five int
      
       for(int i=0;i<5;i++) { // loops until five inputs are entered

           System.out.println("Enter today's sale for store "+ (i+1) +" (negative value not allowed)");

               Store [i] = input.nextInt();//allows user input
               }// end of for

       System.out.println("SALES BAR CHART");

       for(int i =0; i<5 ;i++) { // for loop to print out store number

       System.out.println("Store "+ (i+1) +": ");

       for(int j=0; j < Store [i];j =j+100) { // for loop to print number of asterisks

                   System.out.print("*");
                       }// end of for loop for asterisks
                   System.out.println();
               }// end of for loop
           }//end of main
       }//end of class

Proofs

For this assignment, know that:

An integer is any countable number. Examples are: -3, 0, 5, 1337, etc.

A rational number is any number that can be written in the form a/b, a and b are integers in lowest terms, and b cannot equal 0. Examples are 27, 22/7, -3921/2, etc.

A real number is any number that is not imaginary or infinity. Examples are 0, 4/3, square root of 2, pi, etc.

1. Prove by cases that for all real numbers | x + y | <= |x| + |y|
2. Prove by contradiction that the average of three real numbers is greater than or equal to at least one of the numbers

JAVA

Write a program that will accept user input for an initial deposit and a total amount the user wants to have, and will output the number of years it will take to reach his/her goal.

For the basic program, the user will deposit the initial amount in a new account, and then the account will receive interest, compounded MONTHLY, at a rate of 0.5%.

Anna is a young ambitious programmer working for a small company developing software for web based services in the health area, with a focus on support to remote aboriginal communities. To further her career Anna undertakes additional tertiary study, with support from her manager, Brian. This study includes topics covering computer ethics, and issues relating to the impact of ICT on different communities. On her current project, Anna develops a new user interface, which has a strong focus on accessibility for remote communities, especially considering the type of technology likely to be used. She also pays special attention to the use of cultural images in the interface, to avoid those which may be distressing or offensive to aboriginal users. The new system is a great success and Anna’s contribution is recognised by her company, through an Employee of the Month Award. The company also receives a national business award for its contribution to the positive use of ICT in aboriginal communities. Brian takes all of the credit for this, and Anna receives no acknowledgement for her efforts. Source:
