- (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(Mathematical functions) a model of worldwide population, in billions of people, is given by this formula. Population = 6.0e0.02t Where t is the time in years (t=0 represents january 2000 and t = 1 represents january 2001). Using this formula, write a c++ program that displays a yearly population table for the years january 2005 through January 2010.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++) How many comparison is needed if you want to search 65 in 100 numbers if you use sequential search? And How many comparison is needed if you use binary search, please list the detailed process of how you get the result.arrow_forward(C++) Request a dollar amount as an integer (i.e. $5.43 is input as 543). If one were to convert this dollar amount into the smallest possible number of coins how many dimes would there be? Use division and modulo operations to code a solution for this problem given any dollar amount as input. Example Output (input in bold italics) Enter a dollar amount as an integer: 285 Optimal number of dimes: 1arrow_forwardProblem 2. (Playing the Waltz) Write a program called playwaltz.py that accepts from standard input, a sequence of 32 integers representing the 32 measures of a waltz, and plays the waltz to standard audio. Before playing any audio, your program must check if the inputs are correct, and if they are not, must call sys.exit (message) to exit the program with an appropriate error message. The following errors must be handled: • If the number of measures is not 32, exit with the message "A waltz must contain exactly 32 measures". • If a minuet measure is not from [1,176], exit with the message "A minuet measure must be from [1, 176]". • If a trio measure is not from [1,96], exit with the message "A trio measure must be from [1, 96]". - "/vorkspace/project3 $ python3 generatewaltz.py < data/mozart.txt | python3 playwaltz. py Directions: • Read the waltz measures from standard input into a 1D list. • Handle the input errors described above. • Play each of the first 16 minuet measures by…arrow_forward
- (C programming) write a program to display the odd numbers between x and y by using while loop.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 PROGRAMMING ONLY) 2. Weird Treasure Chestby CodeChum Admin I'm now in the middle of the jungle when I saw this weird treasure chest. It seems that if I properly place the address of a certain number, I get a very weird result! Instructions: In the code editor, you are provided with a treasureChestMagic() function which has the following description:Return type - voidName - treasureChestMagicParameters - an address of an integerDescription - updates the value of a certain integer randomlyYou do not have to worry about how the treasureChestMagic() function works. All you have to do is ask the user for an integer and then call the treasureChestMagic() function, passing the address of that integer you just asked.Finally, print the updated value of the integer inputted by the user.Input 1. An integer Output Enter n: 10Treasure Chest Magic Result = 13arrow_forward
- (C++ Programming language) There are following two major issues associated with cpp programs:• When a program is terminated, the entire data is lost. • If you have to enter a large number of data, it will take a lot of time to enter them all in the different programs.Suggest a solution and elaborate the same with the help of suitable examples.arrow_forward(C++) 1. Ask the console for a three-digit integer. To extract each digit in reverse order, use division and modulo procedures. Determine whether each digit is a factor of the original integer.
