Computer Science "Add a function to your pixart module that draws a single pixel of the correct color based on the supplied character.

Congrats! You work for Zillow now. Your first task is to write an algorithm that recommends apartments based on a user’s preferences. Zillow offers the following three properties for rent: Apartment A – 600 square feet, pets allowed, $1400/month Apartment B – 800 square feet, no pets, $1600/month Apartment C – 1000 square feet, pets allowed, $1800/month Write an algorithm for a program that does the following: Prompt the user for the minimum square footage they will accept, how many pets they have, and the maximum price they’d pay per month, and then calculate and output the apartments that match their preferences. If there is no apartment that matches their preferences, print out "No matches, sorry!". Make sure the inputs are valid--negative square footages, prices, and pet numbers don’t make sense!
I'm trying to write a program in java that takes user input for the size of the sun in inches and outputs a table of solar system values based on the size of the sun given in inches. Camilla was asked by her niece, to help her with her project for the 7th grade Science Fair. She was overjoyed to have been asked to help. Her niece wanted to build a scale model of the solar system. Her niece, remembers having received a planisphere in 4th grade science class. But, she had lost it. But, she remembered that there were instructions on the planisphere for how to build a scale model of the solar system based on the Sun being the same size as the star circle. Her niece had always wanted to build that model and she thought that this would be the perfect Science Fair project. Camilla remembers having seen that planisphere. She and her niece guessed that the star circle in the planisphere was about 8 inches in diameter. Camilla was excited because she had always been interested in…

Scenario: I am trying to create a recursion function that takes a number from the user. That number then goes through to equations where it squares the number and takes the square root of it. Then, that value is supposed to be sent back through the function, through the same equations. Then, I am trying to output the value of each iteration. The amount of iterations is a random number. This code is in C++ and I am using Visual Studio 2023. I have attached the code I, myself, typed and picture of the output. Also, this is a header file that is being called from my source.cpp file (case 5 in switch case). That is why I am entering 5 as the first input when I run the program. Problem: The output only shows one iteration of calculation, then goes straight back into taking an input from the user. What am I doing wrong?
