8. If P is the population of the first day of the year, B is the birth rate and D is the death rate, the estimated population at the end of the year is given by formula: Pn + (B * Pn ) / 100 – ( D * Pn ) / 100 The population growth rate is given by the formula: B - D Write a program that prompts the user to enter the starting population, birth and death rates and n, the number of years. The program should then calculate and print the estimated population after n years. Your program must contain the following functions: GrowthRate: This function takes as its parameters the birth and death rates and returns the population growth rate. Estimated Population: This function takes as its parameters the current population, population growth rate and n, the number of years. It returns the estimated population after n years. Your program should not accept negative birth rate, negative death rate or population less than 2.

For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.
a. Write a program named CheckMonth that prompts a user to enter a birth month. If the value entered is greater than 12 or less than 1, display an error message; otherwise, display the valid month with a message such as 3 is a valid month. b. Write a program named CheckM0nth2 that prompts a user to enter a birth month and day. Display an error message if the month is invalid (not I through 12) or the day is invalid for the month (for example, not between 1 and 31 for January or between I and 29 for February). If the month and day are valid, display them with a message.
1. Federal law requires that hourly employees be paid “time-and-a-half” for work in excess of 40 hours in a week.For example, if a person’s hourly wage is $12 and he or she works 60 hours in a week, the person’s gross pay shouldbe (40 *12) + (1.5 *12 * (60-40)) = $840.Write a program that requests the floating number of hours a person works in a given week and the person’s hourlywage as input, and then displays the person’s gross pay. Save it as overtimePay.py

stoppingDistance = speed * (2.25 + speed / 21)Write a program which determines whether a vehicle’s tailgating distance is safe.The program should read in the speed of the vehicle and the vehicle’s tailgatingdistance. The program should then calculate the distance that would be required tostop the vehicle.If the stopping distance is less than the tailgating distance, your programshould print “No problem.” If the stopping distance equals the tailgatingdistance, your program should print “Minor wreck.” If the stopping distanceis greater than the tailgating distance, your program should print “Majorwreck!”

Q3: Write a program in which user is asked to enter two integers (divisor and dividend) and computes the quotient and remainder. To compute quotient and remainder, both divisor and dividend should be integers.
Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved by executingcout << fixed << setprecision(2); once before all other cout statements. Ex: If the input is: 20.0 3.1599 the output is: 3.16 11.85 79.00

Using c++ Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an inpatient or an outpatient. If the patient was an inpatient, the following data should be entered: The number of days spent in the hospital The daily rate Charges for hospital services (lab tests, etc.) Hospital medication charges If the patient was an outpatient, the following data should be entered: Charges for hospital services (lab tests, etc.) Hospital medication charges Use a single, separate function to validate that no input is less than zero. If it is, it should be reentered before being returned. Once the required data has been input and validated, the program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the inpatient data, while the other function accepts arguments for outpatient data. Both functions should return the total charges
