Adding Students to a Club Create an application that displays a list of student names in a ListBox. Use a second empty ListBox to represent the members of a student club. Use a button labeled Addto copy member names from the general list to the club list. Use a button labeled Remove to remove a student from the club list. Keep a running count of the number of names in the club list. The application should perform the following error-checking:• Do not permit the same person’s name to be added twice.• Avoid throwing an exception if the user clicks the Add button before having selected a student name.• Avoid a runtime error if the user clicks the Remove selected member button, without having selected a member name
In "Starting out with visual basic 8th edition programming challenge 5"
Name SearchIn the Chap07 folder of the Student Sample Programs, you will find the followingfiles:• GirlNames.txt—This file contains a list of the 200 most popular names given to girls born in the United States from 2000 through 2009.• BoyNames.txt—This file contains a list of the 200 most popular names given to boys born in the United States from 2000 through 2009.Create an application that reads the contents of the two files into two separatearrays or Lists. The user should be able to enter a boy’s name, a girl’s name, orboth, and the application should display messages indicating whether the nameswere among the most popular
Create a sorted_grades application that can store up to 10 grades in order from highest to lowest in a list. The application should display a menu of options, which include “Enter a grade”, “Delete a grade”, “Display lowest grade”, “Display highest grade”, “Show grades”, and “Quit”. The list should initially contain all zeros (0).
The algorithm for entering a grade is similar to:
Find the appropriate position for the grade so that all grades are still in order from highest to lowest.
Insert the grade
Make certain that length of list remains the same
The algorithm for deleting a grade is similar to:
Find the element containing the grade to delete.
If list empty tell user they can’ delete and if grade doesn’t exist, inform user no grade has been found.
Use del function. Make certain the length doesn’t change and last element =0
Note: You can use the return to exit your function once you have found your element.

- switch_player(): we will allow the players to choose their own names, but for our purposes, it is easier to think of them as number (0 and 1, for indexing purposes). We will display their names to them on the screen, but in the background, we will keep track of them based on their number. This function should take 1 argument, an integer (either 0 or 1) representing the player and should return the opposite integer (1 if 0 is entered and 0 if 1 is entered). This is a simple function, but it will make our code cleaner later. Use your constants!

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.arrow_forwardGroup 2/12 Problem – Population Create an application that predicts the approximate size of a population of organisms.

Use a ListBox to display the population size for each day of the simulation. If the user clicks the Save button, save the current prediction to a file. Group 3/7 Problem – Dice Simulatorarrow_forward
