Calculate the sum of numbers within an arrayYou can create your own array of numbers but consider trying this problem with a few different sets to verify your solution. Have one array with negative and positive numbers and another with integers and decimals. You could also try using arrays of different lengths. If you're feeling comfortable with this, try the slightly more challenging bonus challenge below. Bonus intermediate challenge: Create a function that can return the sum of a particular column or row number in a table.

- Jumping in the Mega Millions fever, your lab is to write a program that simulates the Mega Millions lottery draw. Your program must have an array of five integers named winningNumbers, with a randomly generated number in the range of 0 through 9 for each element in the array. Your program should ask the user to enter five numbers and should store them in a second integer array named player. The program must compare the corresponding elements in the two arrays and count how many numbers match. For example, the following shows the winningNumbers array and the Player array with sample numbers stored in each. There are two matching elements, elements 2 and 4. Once the user has entered a set of numbers, the program should display the winning numbers and the player's numbers and tell how many numbers matched. Here is an example of the possible output from your code: /* SAMPLE RESULTS RUN 1 Submit the five numbers of your lottery number, separated by blanks: 93441 Winning number: 30766 Your…The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below.
