Program Plan Intro
Linked list:
- Linked list denotes a linear data structure.
- The elements are not stored at contiguous locations; the elements are linked using pointers.
- It stores linear data of similar types not like arrays.
- The size of linked list can be changed based on requirement.
- It is represented by a pointer to first linked list node.
- The first node denotes a head.
- If linked list is empty, value of head is NULL.
- The node in a list has two parts, data and pointer to next node.
Given code:
//Define a structure
struct ListNode
{
//Declare variable
string item;
//Declare variable
int count;
//Define next node
ListNode *link;
};
//Create instance
ListNode *head = new ListNode;
Explanation:
- The “ListNode” defines a structure with “item” and “count” as members.
- It has a pointer “link” to next element of list.
- The “ListNode *head = new ListNode” creates an instance of structure and a new element is created.
Complete program:
//Include libraries
#include<iostream>
#include<string>
//Use namespace
using namespace std;
//Define a structure
struct ListNode
{
//Declare variable
string item;
//Declare variable
int count;
//Define next node
ListNode *link;
};
//Create instance
ListNode *head = new ListNode;
//Define main method
void main()
{
//Assign value
head->item = "Wilbur's brother Orville";
//Display value
cout << head->item << endl;
//Pause console window
system("pause");
}
Explanation:
- The “ListNode” defines a structure with “item” and “count” as members.
- It contains a pointer “link” to next element of list.
- The “ListNode *head = new ListNode” creates an instance of structure and a new element is created.
- The main method assigns value to “item” to head of linked list.
- The value of head of linked list is been displayed.

Scenario
You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement.
You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds.
The conversions are as follows:
1 kilogram = 35.274 ounces
1 kilogram = 2.20462 pounds
1 pound = 0.453592 kilograms
1 pound = 16 ounces
1 ounce = 0.0283 kilograms
1 ounce = 0.0625 pounds
For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters. In the code window you…

The good news is that management approved the payroll system project this morning.

The bad news is that the system must be installed by January 1st in order to meet new federal reporting rules, all expenses from now on must be approved in advance, the system should have a modular design if possible, and the vice president of finance would like to announce the new system in a year-end report if it is ready by mid-December."

Signed Integers Unsigned binary numbers work for natural numbers, but many calculations use negative numbers as well. To deal with this, a number of different methods have been used to represent signed numbers, but we will focus on two's complement, as it is the standard solution for representing signed integers. 2.1 Two's complement • Most significant bit has a negative value, all others are positive. So, the value of an n-digit -2 two's complement number can be written as: Σ2 2¹ di 2n-1 dn • Otherwise exactly the same as unsigned integers. i=0 - • A neat trick for flipping the sign of a two's complement number: flip all the bits (0 becomes 1, or 1 becomes 0) and then add 1 to the least significant bit. • Addition is exactly the same as with an unsigned number. 2.2 Exercises For questions 1-3, answer each one for the case of a two's complement number and an unsigned number, indicating if it cannot be answered with a specific representation. 1.
