Question
help me solve this in c++ please
Write a program that asks the user to enter a list of numbers from 1 to 9 in random order, creates and displays the corresponding 3 by 3 square, and determines whether the resulting square is a Lo Shu Magic Square.
Notes
- Create the square by filling the numbers entered from left to right, top to bottom.
- Input validation - Do not accept numbers outside the range. Do not accept repeats.
- Must use two-dimensional arrays in the implementation.
- Functional decomposition — Program should rely on functions that are consistent with the
algorithm .
Transcribed Image Text:Lo-Shu Magic Square
loShu.cpp
The Lo Shu Magic Square is a grid with 3 rows and 3 columns as shown below:
492
357
816
The grid contains the numbers 1 through 9 exactly.
The sum of each row, each column, and each diagonal all add up to the same number:
15
492 15
357 15
8 16 15
15
15 15 15

Creating Lo Shu Square
Enter Nine Numbers (1-9)
Number 1: 1
Number 2: 2
Number 3: 2
Error ...
2 is already in the Lo Shu Square. Try again
Number 3: 3
Number 4: 4
Number 5: 5
Number 6: 10
Error ... Invalid number. Try again
Number 6: 6
Number 7: 7
Number 8: 8
Number 9: 9

- Programming Language: C++ Please use the resources included and provide notes for understanding. Thanks in advance. Code two functions to fill an array with the names of every World Series-winning team from 1903 to 2020, then output each World Series winner with the number of times the team won the championship as well as the years they won them. The input file is attached, along with the main function and screenprint. Please note team names that include two words, such as Red Sox, have an underscore in place of the space. This enables you to use the extraction operator with a single string variable. The following resources are included: Here is main. #include <iostream>#include <fstream>#include<string> using namespace std; // Add function declarations and documentation here void fill(string teams[], int size);void findWinner(string teams[], int size); int main(){ const int SIZE = 118;int lastIndex;string team[SIZE]; fill(team, SIZE);findWinner(team, SIZE); return...arrow_forwardpython: numpy def purchases(transactions): """ QUESTION 7 - A high-end store is trying to evaluate the total amount that customer's spend per transaction.

- Topic: Array covered in Chapter 7 Do not use any topic not covered in lecture. Write a C++ program to store and process an integer array. The program creates an array (numbers) of integers that can store up to 10 numbers. The program then asks the user to enter up to a maximum of 10 numbers, or enter 999 if there are less than 10 numbers. The program should store the numbers in the array. Then the program goes through the array to display all even (divisible by 2) numbers in the array that are entered by the user. Then the program goes through the array to display all odd (not divisible by 2) numbers in the array that are entered by the user. At the end, the program displays the total sum of all numbers that are entered by the user.arrow_forwardPlease written by computer source (java)arrow_forwardWeight Statistics Write a program that monitors monthly weight loss each of 12 months into an array of doubles. The program should calculate and display the total weight loss for the year, the average monthly weight loss, and the months with the highest and lowest amounts.

- Good evening, i am working on this arrays problem and was hoping you could help with it please? (my programming language is c++) Thanks!arrow_forwardProblem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9arrow_forwardC++ Coding: ArraysTrue and False Code function definitions for eoNum() and output(): Both eoNum() and output() are recursive functions. output() stores the even/odd value in an array. Store 0 if the element in the data array is even and store 1 if the element in the data array is odd. eoNum() displays all the values in an array to the console.arrow_forward
- C++ Write the program that outputs the following menu. The program should allow a user to input numbers into an array of integers. The array size should be 10. The first number should be stored in the zero position of the array. The next number should be stored in the next available location. Each option below should be written using a procedure, except Quit. Remember to comment the procedures with (given, task and return). (MENU) 1) Input number. 2) Sort numbers. 3) Output numbers 4) Quit Option 1) Allows the user to input a number and store it into the array. If the array is full no more numbers should be input. When the user select option 1 and the array is full it should output (Memory Full!). This option will only allow one number to be entered. If the user want to input another number they will need to select option 1 again. Option 2) This option should take the array and sort it in ascending order. Use the selection sort to do this.

The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument.
