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.

Please code in python Kiki is making “Happy National Pizza Day” (February 9th) cards for all of her friends. She’s a bit disappointed with the cards not looking special enough, so she decides to add glitter to them to make them look more special. However, she’s short on glitter, so she decides to add glitter selectively. She uses a box with N*N divided sections to store her cards. Each section is huge and each card is small, so she can put multiple cards in a given section and they will never overlap. We model the way that she organizes the cards and adds glitter using two commands: Command 1: 1 x y: add a card to the box in section (x, y). Command n: 2 x1 y1 x2 y2: Add one unit of glitter to each of the cards in the sections from (x1, y2) to (x2, y2). Help Kiki determine the total number of units of glitter that she placed on the cards. Input The first line will contain N (1 <= N <= 500) and C (1 <= C <= 500 ), the square size of the card storage box…
