- (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 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++ Programming) Question 1: Write a program which the user is asked to enter two integers. Then, the sum of these two integers and displayedon the screen. Question 2: Design a program using “For Loop” that will output the “seven” times table as follow:7 x 1 = 77 x 2 = 147 x 3 = 21:7 x 10 = 70arrow_forward
- 12. (Data processing) Write, run, and verify a C++ program that accepts three numbers as input, and then sorts the three numbers and displays them in ascending order, from lowest to highest. For example, if the input values are 7 5 1, the program should display them in the numerical macorder 1 5 7.arrow_forward( C++ ) Write a program in C++ to print the college name, location and area code (Higher College of Technology – Al Khuwair – 33) using symbolic constants COLLEGE, AREA, CODEarrow_forward(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs increment the counter variable that's keeping count of the 1s that occur; and so on. finally display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.arrow_forward
- (C++ CODE) A new video store in your neighborhood is about to open. However, it doesnot have a program to keep track of its videos and customers. The storemanagers want someone to write a program for their system so that thevideo store can operate.The program will require you to design 2 ADTs as described below: (C++)arrow_forward(c++) Ask the user to provide a single alphabetic character. Print Vowel or Consonant depending on the input. If the u not a letter (between a and z or A and Z) or is a string of length > 1, print an error.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++) 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++ 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 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
