Create a class named INVOICE that contains fields for an item number, name, quantity, price, and total cost. Create instance methods that set the item name, quantity, and price. Whenever the price or quantity is set , recalculate the total (price times quantity ). Also include a DISPLAYLine() method that displays the item number, name, quantity, price for each INVOICE. Save the class as INVOICE.java
Sample output
item # : 111
Item name: chips
Quantity:2
Price: 1.00
Total Cost: 2.00
Name your database using your names as: “db_first_last_studentNumber”. ∙ Name all your tables in your database using this format: “tbl_tableName”. ∙
∙ This mini-project is worth 20 marks (10 marks for a working GUI, 10 marks for performing CRUD operations on a DB through the GUI).
Milestone:
For this unit, you are required to develop a GUI application using Java. The application should connect to a database and should be able to perform any CRUD operation.
Main goal:
Develop a Java application with GUI for a primary school called Duka.
Functional Requirements:
The application should allow:
i. A shop attendant to be able to login to upload stock of items (with prices). ii. A buyer be able to search for items, get their prices and make an order.
Non-functional Requirements:
The application should:
i. Have a user-friendly GUI for both shop attendant and buyer.
ii. Not crash in case a user makes a mistake, instead it should provide a clarification/warning.
Write a program in c++ that initiative an array of given 10 real numbers. The program should sort the number in awaiting / descending order using bubble sort method. It should print the given list as well as sorted list
Matrix Rotations
You are given a square matrix A of dimensions NxN. You need to apply the below given 3 operations on the matrix A.
Rotation: It is represented as R S where S is an integer in {90, 180, 270, 360, 450, ...} which denotes the number of degrees to rotate. You need to rotate the matrix A by angle S in the clockwise direction. The angle of rotation(S) will always be in multiples of 90 degrees.
Update: It is represented as U X Y Z. In initial matrix A (as given in input), you need to update the element at row index X and column index Y with value Z.
After the update, all the previous rotation operations have to be applied to the updated initial matrix.
Querying: It is represented as Q K L. You need to print the value at row index K and column index L of the matrix A.

Create a program based on the attached 3 outputs below. Using a while loop is required in your program
Sample output 1:
Choices
E or e for Even
O or o for Odd
X or X for Exit
Enter your choices: e
.........This program is for Multiplication of even numbers........
Enter a number:20
1 * 2=2
2 * 4=8
3 * 6=18
4 * 8=32
5 * 10= 50
6 * 12=72
7 * 14=98
8 * 16=128
9 * 18=162
10 *20= 200
Sample output 2:
Choices
E or e for Even
O or o for Odd
X or X for Exit
Enter your choice:o
.....This program is for Multiplication of Odd numbers....
Enter a number:10
1 * 1=1
2 * 3=6
3 * 5=15
4 * 7=28
5 * 9=45
Sample output 3:
Choices
E or e for Even
O or o for Odd

Enter your choice:X
Your program will now exit.
The tap code, sometimes called the knock code, is a way to encode text messages on a letter-by- letter basis in a very simple way. Tap code has been one of the most basic communication protocols and still used to convey SOS messages and other urgent communication. The tap code uses a 5×5 grid of letters representing all the English alphabets, see Figure 1. To communicate the word "water", the cipher would be the following (with the pause between each number in a pair being shorter (single space) than the pause between letters (two spaces)),
Your task is to design a program that can
i) convert any given string into a Tap code sequence
Prototype: char* convertToTapCode(char*)
ii) and A Tap code sequence to a string (char*)
Prototype: char* convertToString(char*)
Note: You are not authorized to use string data type; however, you can use char*
Addition of Big Integer
In this problem, you have to take two char arrays of numbers (e.g., “1203009954” and
“109876201453”) from the user and add these two numbers and store answer in a third char array digit by digit (“111079211407”).
char* additionOfBigInteger(char * Num1, char* Num2)
Subtraction of Big Integer
In this problem, you have to take two char arrays of numbers (e.g., and “1203009954”
“109876201453”) from the user and subtract these two numbers and store answer in a third char array digit by digit (“-108673191499”).
char* subtractionOfBigInteger(char * Num1, char* Num2)
Multiplication of Big Integer
In this problem, you have to take two char arrays of numbers (e.g., and “1203009954”
“109876201453”) from the user and multiply these two numbers and store answer in a third char array digit by digit (“132182164055668263162”).
char* multiplicationOfBigInteger(char * Num1, char* Num2)
Write a C++ recursive function PrintPattern1 to print following pattern using recursion. No
loops allowed whatsoever, and you can write other helping (recursive) functions. For example, calling your function with these argument PrintPattern1(1,10) should print following pattern. Your function prototype must be as follows:
void PrintPattern1(int start, int end);
pattern:
