- (Apartment problem) A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say, $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program in C++ that prompts the user to enter: The total number of units. The rent to occupy all the units. Amount to maintain a rented unit. The increase in rent that results in a vacant unit. The program then outputs: The number of units to be rented to maximize the profit The maximum profit Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of 2.arrow_forward(C++)Write a program that will allow a student to compute for his equivalent semestral grade. The program should ask the user should input his/her first name, last name, middle initial, and student number. After, inputting everything above, the output will clear the current screen and a new screen should open. A sample program that would clear a screen is included below for your reference. On the new screen, the user will then be greeted "Welcome, <firstname>! (i.e. Welcome, Louie!)" The program will then ask for the prelim grade, midterm grade and final grade of the student. The program should only accept grades 100 and below. After getting the three grades, the program should compute for the semestral grade. The computation of the semestral grade is as follows: 30%*PrelimGrade + 30%*midtermgrade + 40%finalgrade After inputting all the grades, the screen should clear again and will proceed to another screen. The new screen should output should output the following (this is…arrow_forward(C++ OOP) We have a house with 3 rooms.We need the user to enter 1 integer as the window number, 2 doubles as depth and width of the room, 1 double as the useless area, 1 boolean as the door's opening direction (e.g. 0 is outward).Program will compute and print the air condition as a string and the total useful area of the house as a double. Calculating the air condition: Name it air_c. Divide the useful area by the window number. If air_c >20, output "bad". If air_c <11 output "good". If 11<=air_c<=20, output "ideal". Attention: If the window number is 0, air condition is bad. Calculating the useful area of room: Width*Depth-(useless area)if the door is inward;Width*Depth-(useless area)-0.8The worst air condition of the 3 is the final air condition of house. --- 1)The information about the home must be all private within a class.2)The class must get these inputs within constructor func.3)Calculating the useful area of a room must be done within a function of a class.4)Air…arrow_forward
- (c program only) 2. Jack `N Poyby CodeChum Admin Jack `N Poy is a very common game since our childhood days. Just thinking about it makes me reminisce how I crushed my cousin in this game until he cried ? I want to feel the glory again of being very good at something. Could you help me recreate the game? It's really simple. In Jack `N Poy, there are two players who both select either one of the following options: RockPaperScissors The winner is selected depending on the following rules: Rock beats ScissorsScissors beats PaperPaper beats RockIf both players chose the same option, then it's a tie Instructions: In the code editor, you are provided with an enum called option which contains three possible named values:ROCK - 'r'PAPER - 'p'SCISSORS - 's'Your task is to ask two users for there chosen options. And then based on their options, determine the winner.Input 1. Option selected by Player 1 2. Option selected by Player 2 Output If Player 1 wins, print the message "Player 1…arrow_forward(c++) Write a program that takes user input describing a playing card with the following shorthand: A = Ace 2...10 card values J = Jack Q = Queen, etc. D = Diamonds S = Spades. etc. Ex. if the user enters QS then your program responds with Queen of Spadesarrow_forward(C++) Write a function definition called quotient that takes as its parameters two decimal values, numer and denom, to divide. Remember that division by 0 is not allowed. If division by 0 occurs, display the message "NaN" to the console, otherwise display the result of the division and its remainder.arrow_forward
- (C++) Write a program with total change amount as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Penniesarrow_forward(C++) 2. Request a character from the console. Use an if/else to output if the character is an uppercase letter, a lowercase letter, or neither a letter nor a number. Example 1 Output (input in bold italics) Input a character: A A is an uppercase letter. Example 2 Output (input in bold italics) Input a character: k k is a lowercase letter. Example 3 Output (input in bold italics) Input a character: 5 5 is a number Example 4 Output (input in bold italics) Input a character: # # is not a number or a letterarrow_forward(C PROGRAMMING ONLY) 1. Dealing With Monthsby CodeChum Admin We're done dealing with days. It's time to step up and now deal with months! Instructions: In the code editor, you are provided with a code in the main() which has 12 printf's. Each printf prints a month with its corresponding value. For this program, January is 1, February is 2, March is 3, and so on. When you run the initial code, you will encounter errors because these month names that have been printed don't exist yet.Your task is to create an enum data type which contains these month names as values so that when we run the code, there will be no more error.Do not edit anything in the main(). Output January = 1February = 2March = 3April = 4May = 5June = 6July = 7August = 8September = 9October = 10November = 11December = 12arrow_forward
- PROBLEM 5 (LOOP/ITERATION) Use do while. A PRIME number is a number whose factors are one and it itself. A COMPOSITE number is a number with at least three factors, and sometimes a lot more. Make a C program that will input a number and determine if the number PRIME or COMPSITE.
