C++ Programming Exercise: 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 that prompts the user to enter: a. The total number of of units. b. The rent to occupy all the units. c. The increase in rent that results in a vacant unit. d. Amount to maintain a rented unit. The program then outputs the number of units to be rented to maximize the profit.

(Data processing) Years that are evenly divisible by 400 or are evenly divisible by 4 but not by 100 are leap years. For example, because 1600 is evenly divisible by 400, 1600 was a leap year. Similarly, because 1988 is evenly divisible by 4 but not by 100, it was also a leap year. Using this information, write a C++ program that accepts the year as user input, determines whether the year is a leap year, and displays a message telling the user whether the entered year is or is not a leap year.
(Data processing) Write C++ code sections to make the following decisions: a. Ask for two integer temperatures. If their values are equal, display the temperature; otherwise, do nothing. b. Ask for character values letter1 and letter2, representing uppercase letters of the alphabet, and display them in alphabetical order. c. Ask for three integer values, num1, num2, and num3, and display them in decreasing order.
(Statistical) In many statistical analysis programs, data values considerably outside the range of the majority of values are simply dropped from consideration. Using this information, write a C++ program that accepts up to 10 floating-point values from a user and determines and displays the average and standard deviation of the input values. All values more than four standard deviations away from the computed average are to be displayed and dropped from any further calculation, and a new average and standard deviation should be computed and displayed.
(Thermodynamics) a. Design, write, compile, and run a program that determines the work,W, performed by a piston engine providing a force of 1000 N over a distance of 15 centimeters. The following formula is used to determine the work performed: W=Fd F is the force provided by the piston in Newtons. d is the distance the piston moves in meters. b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the work performed by six pistons, each providing a force of 1500 N over a distance of 20 centimeters.
(Modify) a. Modify the program you wrote for Exercise 7 to provide the mass of a person as an output, given his or her weight as an input to the program. Use your program to determine the mass of a person who weighs 140 lbf on Earth. b. Modify the program written for Exercise 7a to also output the person’s weight on Mars and the moon. The pull of gravity on Mars is 12.54ft/sec2=3.728m/s2,andonthemoonis5.33ft/sec2=1.625m/s2.
(Computation) Among other applications, Pascal’s triangle (see Figure 7.22) provides a means of determining the number of possible combinations of n things taken r at a time. For example, the number of possible combinations of five people (n = 5) taken two at a time (r=2)is10. Each row of the triangle begins and ends with 1. Every other element in a row is the sum of the element directly above it with the element to the left of the one above it. That is, element[n][r]=element[n1][r]+element[n1][r1] Using this information, write and test a C++ program to create the first 11 rows of a twodimensional array representing Pascal’s triangle. For any given value of n less than 11 and r less than or equal to n, the program should display the correct element. Use your program to determine in how many ways a committee of 8 can be selected from a group of 10 people
(Conversion) a. Design, write, compile, and run a C++ program to convert temperature in degrees Fahrenheit to degrees Celsius. This is the equation for this conversion: Celsius=5.0/9.0(Fahrenheit32.0) Have your program convert and display the Celsius temperature corresponding to 98.6 degrees Fahrenheit. Your program should produce the following display (replacing the underlines with the correct values): For a Fahrenheit temperature of ___ degrees, the equivalent Celsius temperature is ___ degrees. b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to convert 86.5 degrees Fahrenheit to its equivalent Celsius value.
(Conversion) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and the corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet. b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data. c. Modify the program written in Exercise 6a to request the starting meter value, the ending meter value, and the increment. Instead of the condition checking for a fixed count, the condition checks for the ending meter value. If the number of iterations is greater than 20, have your program substitute a default increment of (ending value - starting value) / 19.
