Exercise 6:
Write a program that reads from the user three pieces of information: The current population of a country, the annual birth
rate of the country, and its annual death rate. The program should then calculate the expected population for the following
year and display the results as shown in Figure 6.
Please note that population for the following year is calculated as sum of the current population, and the number of births
by the end of the year minus the number of deaths by the end of the same year.
Name your program Lab3_Id_ex6.py, where Id is your university Id. Include the design of your solution as comments
at the beginning of your program. Test your solution with different input data.
Please enter the current population of the country: 1800000
Please enter the birth rate: 0.017
Please enter the death rate: 0.005

Program 2:
Write a program that asks the user for a word or phrase.
Check to see if it is a palindrome. A palindrome is a word that is spelled exactly the same forward and backwards such as radar or noon.
Your program must also take case into account. If the user types Radar, it must still return that it is a palindrome. Do not worry about palindromes with spaces.
You do not need to put any code in static methods, you do not need to worry about try/catch blocks, and you do not need to make the program run more than once.
Test values that I will use in class:
Noon palindrome
tacocat palindrome
Hello not a palindrome

PROBLEM:Write a program that prompts the user to input any digit then swap the position of the first and the last digit. Next, the user will be prompt to select what arithmetic operation he/she want to employ on the first and last digit based on the following choices:
1. Sum of their square
2. Product of their square root
3. Square of their product
The output will display the result of the arithmetic operation followed by the digit with a swapped position of “first” and “last” digit. Then finally display the equivalent uppercase alphabet for the first digit and lowercase alphabet for the last digit respectively after swapping.
Note:
1. If the last digit of the inputted digit from the user is zero, it must display that there is no equivalent alphabet for that digit.
2. If the user chooses arithmetic operation No.2, format the output to three decimal places

The program asks the user how many times a week they eat at the student cafeteria. Then it asks for the price of a typical student lunch, and for money spent on groceries during the week. Based on this information the program calculates the user's typical food expenditure both weekly and daily. The program should function as follows: How many times a week do you eat at the student cafeteria? 4 The price of a typical student lunch? 2.5 How much money do you spend on groceries in a week? 28.5 Average food expenditure: Daily: 5.5 euros Weekly: 38.5 euros Sample outputarrow_forwardBody Mass Index (BMI) is a measure of health on weight. It can be calculated by taking your weight in kilograms and dividing by the square of your height in meters. Write a program which prompts the user to enter the weight in kgs (integer value) and height in feet and inches (both integers) and then calculates the BMI of the person. Your program first need to convert inches to meters (i.e. inches * 0.0254) and then use the following formula to calculate BMI: weight kilogram / (height_meter)^2 Your program displays the BMI value in two decimal places and the corresponding status as shown in the examples below. Note that one inch is 0.0254 meters and 1 foot is 12 inches.

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.…arrow_forwardGiven the sample code above in generating a random number. Create a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don't display the computer's choice yet.) 2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer.) 13. The computer's choice is displayed. 4. A winner is selected according to the following rules: a. If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) b. If one player chooses scissors and the other player chooses paper, then scissor wins. (Scissors cuts paper.) c. If one player chooses paper and the other player…arrow_forward
- You are working for a lumber company, and your employer would like a program that calculatesthe cost of lumber for an order. The company sells pine, fir, cedar, maple, and oak lumber.Lumber is priced by board feet. One board foot equals one square foot that is one inch thick. Theprice per board foot is given in the following table: (image 1) The lumber is sold in different dimensions (specified in inches of width and height, and feet oflength) that need to be converted to board feet. For example, a 2 x 4 x 8 piece is 2 inches wide, 4inches high, and 8 feet long, and is equivalent to 5.333 board feet (2 * 4 * 8 = 64, which whendivided by 12 = 5.333 board feet). An entry from the user will be in the form of a letter and fourinteger numbers. The integers are the number of pieces, width, height, and length. The letter willbe one of P, F, C, M, O (corresponding to the five kinds of wood) or T, meaning total. When theletter is T, there are no integers following it on the line. The program…arrow_forward4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forward(Modify) a.

- Problem 7: Guess the price of the car!? You will implement a variant of the number guessing game we played in lecture. In this variant, you will ask the user to guess the price of a $42,500 car. Let's assume that the player knows the price of the car is rounded to the nearest $500. If a player's guess is not exactly correct, your program will tell them they are either too high or too low. The player will get as many guesses as they need to guess the price of the $42,500 car. However they will only win the game if they used 5 or fewer guesses. Here are two examples of how the program should work for both cases: Guess the price and win the prize! Enter your guess:50000 Too high! Enter your guess:40000 Too low! Enter your guess:45000 Too high! Enter your guess:42500 You won the car! Guess the price and win the prize! Enter your guess:46000 Too high! Enter your guess:45000 Too high!
