Question
In Lab 2, you created a menu for a simple calculator
Write a program (or modify the one written for Lab 2) that displays the following menu and prompts the user for a selection. Once the selection has been made, display the selection back to the user. Then, ask the user for two numbers and perform the selected operation (+, -, *, /). Display the results back to the user (e.g. 2 + 3 = 5). When dividing, display an error message if the second number (denominator) is 0.
1) Add two numbers
2) Subtract two numbers
3) Multiply two numbers
4) Divide two numbers
9) Exit program
The program should:
- contain header comments as shown in class
- display a "hello" message before presenting the menu
- display the menu
- prompt the user for selection
- display the selection back to the user
- if the selection was invalid, display error message to user and then go to goodbye message
- if the selection was valid, prompt the user for two numbers
- if the operation is division, and the second number is 0, display error message to user and then go to goodbye message
- for any other scenario, perform the operation and display the results
- display a "goodbye" message before exiting the program
HINT: The switch statement is ideal for menu-driven programs...
SAMPLE OUTPUT FOR VALID MENU SELECTION
You entered 2, subtract two numbers
SAMPLE OUTPUT FOR INVALID MENU SELECTION
You entered 5, an invalid selection
SAMPLE OUTPUT FOR ADDPlease enter two numbers, separated by a space: 2 3
2 + 3 = 5
SAMPLE OUTPUT FOR DIVISION ERRORPlease enter two numbers, separated by a space: 2 0
Division by zero is not possible

- 2.Create a visitors application that prompts the user for the number of visitors each day for the past 5 days and then displays the average number of visitors per day. (use & to accept new value) Use a for-loop for this question (1 to 5 , 5 iterations). The application output should look like same as following: Enter number of visitors on day 1: 150 Enter number of visitors on day 2: 220 Enter number of visitors on day 3: 180 Enter number of visitors on day 4: 300 Enter number of visitors on day 5: 320 The average number of visitors is 234arrow_forwardcreate a JAVA PROGRAM as a Currency Converter program. The program performs Currency Exchange operation between Saudi Riyals R, Dollars $, Euro € and British Pounds £. The program firstly shows a menu to the user which allows the user to choose one of the possible currency exchange operations and the last option in the menu should allow the user to end the program (see figure1). The menu should be like as figure 1. If the user enters a wrong choice, an error message should appear and the program asks the user to re-enter a correct number. When the user selects an operation, the program do the following: Prompt user to enter the amount to be changed Input amount Calculate and print the result. Once the user presses any key, the menu appears again and the user can choose a new operation. Your output should be similar to the result in figure 2. Note: Currency change rate is assumed to be known in your program. For example, to convert from Riyals to Euro, change rate = 0.22751799.…arrow_forwardWrite the code to allow the user to enter a list of positive integers via input boxes and add each number entered to the lstNums list box.

- Fill in the first blank to compute the total number of calories for all items on the menu and fill in the 2nd blank to compute the number of items on the menu:arrow_forwardIt is given 12 balls that are all the same weight except for one that is heavier or lighter. Additionally, it is provided with a two-pan balance. In each scenario, the balance is used. You may place any number of the 12 balls on the left pan and the same number on the right pan and press a button to begin weighing; three alternative results exist: the weights are equal, the balls on the left are heavier, or the balls on the left are lighter. Develop a technique for determining which ball is the odd one out and whether it is heavier or lighter than the others using the fewest feasible uses of the balance. Solve the weighing issue for the situation of 39 balls, one of which is known to be strange.arrow_forwardWrite a program that uses the following menu to keep track of student information: 1) Enter a student 2) Quit If the user chooses 1, prompt the user to enter a grade level (to be chosen from the given menu) and a test score.

Input validation: • The user must choose valid options from the menus. • The user must enter a test score between 0 and 100.arrow_forward
- You are a Chemistry major who has to create a program for first time chemistry lab users. The Erlenmeyer flask contains a nitric acid solution. When the student presses a button, 0.5 mL of NaOH solution can be added to a buret, which is set up over the Erlenmeyer flask. An indicator is added to the solution being titrated. The indicator is a substance that changes to blue when the reaction is complete (endpoint). You determine the amount of mixture that will cause this reaction to occur. Create a titration simulator that will allow a student to add up to 18 mL of titrant. Notify the student when the mixture turns blue.

If the user guess is higher than the random number, the program should display Too high, try again. If the users 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 generate a new random number so the game can start over. If the user doesn't want to continue the game the user should type an appropriate stop symbol to terminate the program (such stop conditions were discussed in the class). For each game iteration, count the number of guesses made by the user and display them. The program should contain the following functions: check_guess(): this function checks if the user's guess is lower, higher or equal to the random number. random_gen(): function that generates one random number for one game iteration main(): the function where the program…arrow_forwardYou have been hired by a local smoothie shop to a program that will calculate the cost of a smoothie order.

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.
