Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…
Write a program that will check the employees years in service and office. • The user will input number for years and in service and the following offices(IT, ACCT, HR)
f. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…
Write a program that reads in three integers and then determines and prints the largest and the smallest integers in the group. Use only the programming techniques you have learned in this chapter.
The monthly payment for a givenloan pays the principal and the interest. The monthly interest is computed by multiplyingthe monthly interest rate and the balance (the remaining principal). The principalpaid for the month is therefore the monthly payment minus the monthly interest.Write a program that lets the user enter the loan amount, number of years, and interestrate then displays the amortization schedule for the loan. Here is a sample run: Loan Amount: 10000 ↵EnterNumber of Years: 1 ↵EnterAnnual Interest Rate: 7 ↵EnterMonthly Payment: 865.26Total Payment: 10383.21Payment# Interest Principal Balance1 58.33 806.93 9193.072 53.62 811.64 8381.43...11 10.00 855.26 860.2712 5.01 860.25 0.01
Write a program that lets the user guess whether a randomly generated integer would be even or odd. The program randomly generates an inte- ger and divides it by 2. The integer is even if the remainder is 0, otherwise odd. The program prompts the user to enter a guess and reports whether the guess is correct or incorrect.
C++ One way to create a pseudo-random three digit number (and we are including one- and two-digit numbers as well) is rand()%1000. That gives numbers from 000 to 999, which is just what we want. Write a program that generates a random number and asks the user to guess what the number is. If the user's guess is too high then the program should display "Too high, try again." If the user's guess is lower than the random number the program should say "Too low, try again." The program should use a loop that repeats until the user correctly guesses the random number. The program should keep track of the number of guesses the user makes. When the user correctly guesses the random number, the program should display the number of guesses. As specified, have the program tell the player how many guesses were used. A good player should always be able to find a three-digit number in ten or fewer guesses. The programs needs to include a menu that allows the user to select easy (3 digit number),…
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 in-patient or an out-patient. If the patient was an in-patient 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 out-patient 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 re-entered 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 in-patient data, while the other function accepts arguments for out- patient data. Both functions should return the total charges.
In this assignment you will write a program that shows the valid moves of chess pieces. Your program will draw a board with 64 squares using the traditional layout, next ask the user to choose a move, and then, depending on the user's choice, redraw the board with the selected chess piece and its valid moves. Please see the examples of valid moves of chess pieces and the traditional chess board layout below:
Write a program that helps a company manage salaries of its employees. Your program should ask for the number of hours worked and the hourly rate of an employee than, display the salary. This program should allow the user to enter the information of many employees until enters -1. Sample Run: Enter the number of hours worked (-1 to end): 32 Enter hourly rate of the worker: 100 Balary is 03200 Enter the number of hours Worked (-1 to end) : 40 Enter hourly rate of the worker: 5 Balary is 3200 Enter the number of hours worked (-1 to end): 42 Enter hourly rate of the worker: 10 Salary is 0420 Enter the number of hours worked (-1 to end) : -1
The equation of a straight line is written as y = mx + b where m is the slope of the line and b is the value of y when x = 0. If there are two coordinate points of the line are given, then it is very easy to compute the line equation. Also you can find the distance between two points. Problem: Write a program to compute lines equation for a set of lines. The number of lines is read from the user. Each line is computed by generating two points randomly using Point2D API. In addition, distance between two points is computed. The program should display a table which include all information about each line. See sample runs below. Take into consideration: 1. Number of generated lines should be greater than zero. 2. Two point objects are constructed only once. Then just update the location of two points for each line using Point2D API methods. 3. x and y values of each point are generated randomly to be less than 100 and greater than 0. 4. Compute the distance between two points using…
Find the numbers that can be expressed as the product of two nonnegative integers insuccession and print them in increasing order. (For example, 30 is such a number as it can bewritten as the product of 5 and 6 (30=5x6), which are two numbers in succession.) The user shouldspecify a maximum value and the program should print all said numbers smaller than or equal tothat value. The program should keep a count of how many numbers were printed and should output that count ,as well as the numbers
