Exercise 3 Write a program for a system that checks for user authentication. The user must provide a username and password for upto three attempts. The system must check if the username exists in the system. If it exists, display a "Welcome" message. If the username is wrong display the approriate message, "Incorrect username" and allow the user to try again. If the user attempts more than three times, exit the loop and display the message "Login attempted too many times. Please contact your administrator".

Employee view attendance report The employee must be logged in to the system to perform this function. The employee selects the report period (range of dates: from - to). The employee selects "show report". Range of dates for the report must be maximum 3 months, so if the range is invalid, the system displays an error message. The system displays every working day in the report with the status of the employee in this day, which could be one of the following: on time, late, did not come. One actor? One use case name? One class ? Attributes for the class ? One relation between classes ?
Hands-On Project 6-1 In this project you will program the actions of a sign-up form in which users must supply a user name, email address, and password for a new account. Passwords must be at least eight characters long and contain at least one letter and one number. As a validation test, the password must be entered twice to confirm that the user did not inadvertently mistype the password. If the password does not match the required pattern or if the two passwords are not identical, the password field should be flagged as invalid. A preview of the form in which the passwords are mismatched is shown in Figure 6-38. Figure 6-38 Completed Project 6-1 Do the following: Use your code editor to open the project06-01_txt.html and project06-01_txt.js files from the js06 ► project01 folder. Enter your name and the date in the comment section of each file and save them as project06-01.html and project06-01.js, respectively. Go to the project06-01.html file in your code editor and link the…
Using C# in Microsoft Visual Studio create an application that displays the total for a customer’s visit . The application should have the following value-returning methods: OilLubeCharges —Returns the total charges for an oil change and/or a lube job, if any. FlushCharges —Returns the total charges for a radiator flush and/or a transmission flush, if any. MiscCharges —Returns the total charges for an inspection, muf fler replacement, and/or a tire rotation, if any. OtherCharges —Returns the total charges for other services (parts and labor), if any. TaxCharges —Returns the amount of sales tax, if any. Sales tax is 6% and is charged only on parts. If the customer purchases services only, no sales tax is charged. TotalCharges —Returns the total charges. The application should have the following void methods, called when the user clicks the Clear button: ClearOilLube —Clears the check boxes for oil change and lube job. ClearFlushes —Clears the check boxes for radiator flush and…
Example of python code that uses the following: implements authentication for entering notes in an application. Apply input validation whenever the user provides input in the menus of the program.
A bank locker system has one lock and three keys.O=1, indicates the Owners key is open.M=0,indicates the Managers key is off.N=1, indicates the Nominees key is openL=0 means the locker is off.The locker(L) can be open only for the following conditions:If the Manager’s key and nominee’s keys are open but the owner key is close. ORIf the Manager’s and owner’s keys are open but the other key is close. ORIf the Owner’s key is open but the other keys are close. ORIf all keys are open.i. Find the Boolean function for the above systems outputs 2ii. Simplify the output functions using Boolean Algebra. 22.
design pattern question :- Using the state pattern, you have to implement an application that help track the item ordered from online shop. The client orders an item from online shop, then item can go to post office, then it will be delivered to the user home. Or the item after being ordered it goes to the post office, then the user will pick it up from the post office. In both cases; either take the item from the post office or has it delivered to the client's home represents the end of the process. Q1)Draw the state diagram that shows all possible states and transitions? Q2) Write code of the Ordered state? Q3) Write the implementation of the ShopOrder class; most important things are the states declaration, the constructor, a function to return robot state
Instructions: Create a program that simulates a password checker. Use the password that was set in the first part of the program, if the user enters the password correctly it will output Authentication Successful if the user does not answer the password correctly it will say Failed Attempt! Try again Attempt 1 Each failed attempt is recorded. Each time the user fails, output the number of that failed attempt. Enter the password: Failed Attempt! Try again Attempt 1 Enter the password: Failed Attempt! Try again Attempt 2 If the user fails 5 times output: Error! You have exceeded the number of attempts, try again? Y for "yes" or N for "No" The program should allow the user to try and enter the password again. The attempts should reset back to 0.
5- Write a script avenegnum that will repeat the process of prompting the user for negative numbers, until the user enters a zero or positive number. The script will print the average (of just the negative numbers). If no negative numbers are entered, the script will print an error message instead of the average. Examples of executing this script follow: >> avenegnum Enter a negative number: 5 No negative numbers to average. >> avenegnum Enter a negative number: -2 Enter a negative number: -8 Enter a negative number: -9 Enter a negative number: 8 The average was -6.3 >>

GreenLawn a local lawn care company has different pricing policies for its customers. GreenLawn sends out monthly invoices and will give discounts if payments are made within 5 days. The discounting policy is as follow: If the amount of the monthly bill is greater than $300, subtract 4 percent from the invoice; if the amount is between $300 and $100, subtract a 2-percent discount; if the amount is less than $100, do not apply any discount. All bills made via the web automatically receive an extra 3-percent discount. Develop a decision for GreenLawn discounting decisions. Decision Table submission: Include the initial table with all rules, and the most simplified table. Use different colors in the columns to easily show how columns are collapsed/simplified. please do not provideo solution in image format thank you!
