The Account form should be opened in "Modify" mode. 3) Add code to the Login form that validates the user input before allowing the user the access the Home form. For now, just verify the user enters "user1" and "12345" for the username and password respectively.

Description: The program starts by asking the user to select either login (L) or sign up (S) feature. Once the user selects a feature, it asks him for (Card Number, then PIN) and after filling the required information for that feature, it shows the above menu for other features. Otherwise, it keeps asking for the required information. Each feature has to be designed using a separate function and it might be called by other functions including the main function. The description of the login feature, sign up feature, and the above features are given below: Sign up Feature – def create(): this feature allows new user to create an account and it saves his information in txt. The required information to be asked in this feature as follows: Card Number: user will enter a card number and should be four digits, each digit is unique and it should not be repeated in the 4-digits card number.

Using C# in Microsoft Visual Studio create an application 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 is2, 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 can use Button controls, or 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. (Scissors…
Plus x: A first function Assign y with 5 plus x. Ex: If x is 2, then y is 7. If x is 19, then y is 24. Note: Some challenge activities require completing a function (as above), or writing a new function. You can create test calls to the function in the "Code to call your function" window, then press "Run". Try appending this call to that window: IncreaseValue(9) When done writing and testing your function, press "Submit for Assessment", which will automatically apply various test calls to your function.
Specifications: Lions, Tigers, and Bears Pet Clinic needs an application that displays basic services. The application should be designed with checkboxes to select the various services (such as office call, vaccination, grooming, etc). As each service is selected, the charge for the service should display in an associated label. (When the checkmark is removed, the amount should be removed). As each selection is made, the charges should be added into the total (a variable… consider scope), and displayed in a Total Due area on the application (currency format). Align all numeric data appropriately. Consider what should happen when the checkmark is removed. Include at least 8 services that your pet clinic performs. Include a Clear and Exit button. The clear should clear all checkboxes, appropriate labels, and the total variable. Use the standard Microsoft naming conventions for all controls. Include appropriate comments in your code. This is for intro to C# Can't use parse. Thank…
Travel Tickets Company sells tickets for airlines, tours, and other travel-related services. Because ticket agents frequently mistype long ticket numbers, Travel Tickets has asked you to write an application that indicates invalid ticket number entries. The class prompts a ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you drop the last digit of the number, then divide the number by 7, the remainder of the division will be identical to the last dropped digit. Accept the ticket number from the agent and verify whether it is a valid number. Test the application with the following ticket numbers: . 123454; the comparison should evaluate to true . 147103; the comparison should evaluate to true . 154123; the comparison should evaluate to false Save the program as TicketNumber.java.
