- Random Number Guessing Game Create an application that generates a random number in the range of 1 through 100 and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display “Too high, try again.” If the user’s guess is lower than the random number, the program should display “Too low, try again.” If the user guesses the number, the application should congratulate the user and then generate a new random number so the game can start over. Optional Enhancement: Enhance the game so it keeps count of the number of guesses that the user makes. When the user correctly guesses the random number, the program should display the number of guesses.arrow_forwardPopulation Tracker Learning Objective: Using Python Repetition and Loop Statements Problem Description Write a Python program (Console and GUI) that predicts the approximate size of a population of organisms. The application should use text boxes to allow the user to enter the following information: starting number of organisms, the average daily population increase (as a percentage), and the number of days the organisms will be left to multiply. For example, assume the user enters the following values: Starting number of organisms: 2 Average daily increase: 30% Number of days to multiply: 10 The program should display the following table of dataarrow_forwardGPA Calculator Students are concerned about their GPA. They need to calculate it accurately every semester to monitor their progress. Develop a GPA calculator that follows the AOU regulations (AOU-OU Grade Scale) using C# programming language. The application asks the student to enter his numeric grade of each course and the course's credit hours. Accordingly, the application calculates the student's GPA after converting the numeric grade to letter grade. The GPA calculation should produce floating-point results. Display the results rounded to the nearest hundredth. You should store the letter grades of all student's courses in an array. The final grade of the student should be also calculated. Sample I/O Enter the course grade (-1 to end): 93 Enter the course credit hours: 3 Enter the course grade (-1 to end): 74 Enter the course credit hours: 2 Enter the course grade (-1 to end): 60 Enter the course credit hours: 3 Enter the course grade (-1 to end): -1 The grades of your courses…arrow_forward
- PYTHON CODE Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tells the ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not. If the ticket number is valid, save the number to a .txt file called “tickets.txt” and continue to loop your program asking…arrow_forwardComputer Science C# Programming Object Orientation Please use Arrays or ArrayLists where appropriate Implement a menu driven program that has some operations for a food truck. A food truck has multiple food items as well as a menu which contains a selection of the food items which will be sold for that day. A maximum of 10 food items can appear on the menu for any day. For each food item keep a code, description, category, price and quantity in stock (code, description and category are not usually changed). Create a comma delimited text file called "items.txt" for 15 or more food items, indicating the item's description, category, price and quantity in stock. Read all the food items from the text file “Items.txt” Display all the food items available for this food truck. Continuously prompt the user for a food item’s code to be placed on the menu until the menu is full or the user enters -1. Note that only food items which have a positive quantity in stock may be added to…arrow_forwardRock, Paper, Scissors Game Create a application using (C#) in Microsoft Visual Studio 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. (Do not display the computer’s choice yet.)2. The user selects his or her choice of rock, paper, or scissors. To get this input you use clickable PictureBox controls displaying some of the artwork that you will find in the student sample files.3. The computer’s choice is displayed.4. A winner is selected according to the following rules: •If one player chooses rock and the other player chooses scissors, then rock wins. (Rock smashes scissors.)•If one player chooses scissors and the other player chooses paper, then scissors wins.…arrow_forward
- Lap Timer Tool Write a Python (GUI program) that asks the user to enter the number of times that they have run around a racetrack, and then uses a loop to prompt them to enter the lap time for each of their laps. When the loop finishes, the program should display the time of their fastest lap, the time of their slowest lap, and their average lap time.arrow_forwardPopulationCreate an application that predicts the approximate size of a population of organisms. The application should use text boxes to allow the user to enter the startingnumber of organisms, the average daily population increase (as a percentage), andthe number of days the organisms will be left to multiply.

Write an application that allows a user to continuously enter a row and seat request until a sentinel value is entered. If the row or seat number is out of range, issue an error message. Otherwise, determine whether the seat has already been reserved. If so, display an error message. If not, then charge the user $7.50 for a ticket and display a running total of the user’s purchase. When the user enters a sentinel, display the number of seats taken and the number of seats available in the auditorium.arrow_forward
- Slot Machine SimulationA slot machine is a gambling device that the user inserts money into and then pulls a lever (or presses a button). The slot machine then displays a set of random images. If two or more of the images match, the user wins an amount of money that the slot machine dispenses back to the user. Create a program that simulates a slot machine. When the program runs, it should do the following: Asks the user to enter the amount of money he or she wants to enter into the slot machine. Instead of displaying images, the program will randomly select a word from the following list: Cherries, Oranges, Plums, Bells, Melons, Bars To select a word, the program can generate a random number in the range of 0 through 5. If the number is 0, the selected word is Cherries; if the number is 1, the selected word is Oranges; and so forth. The program should randomly select a word from this list three times and display all three of the words. If none of the randomly selected words match, the…arrow_forwardC CODE: create a program that will test the user’s proficiency in solving different types of math problems. The program will be menu-driven. The user will select either addition, subtraction, multiplication, or division problems. The program will then display a problem, prompt the user for an answer, and then check the answer displaying an appropriate message to the user whether their answer was correct or incorrect. The user will be allowed 3 tries at each problem. The program will also keep statistics on how many problems were answered correctly. add functions to allow the user to select problems of varying degrees of difficulty In the next Week, you'll need to add functionality to also keep statistics on the number of correct answers vs. the total number of problems attempted. So now let’s add the code for the remaining functions: We’ll start by inserting code to ask the user if they want to see problems that are easy, medium, or difficult.
