*Using C# in Microsoft Visual Studio* create an application that lets the user enter a nonnegative integer and then uses a loop to calculate the factorial of that number. Display the factorial in a label or a message box. If the input is nonnumeric your program SHOULD NOT CRASH but display a message “”non numeric input”. If the input is negative display the message “”negative numbers are invalid.
Even though the EXIT clause can be used in any type of loop, it is considered good form to use the EXIT clause only in basic loops. Answers: Yes No
This program requires the student to create a programming loop. The program's loop with loop between 5 and 50 times. Each loop will represent one week of the user eating and buying food. Each week the user will input the amount he or she spent on food. If the person spends more than $250 then the program will output "You are going to get fat." If the person spends less than $50.55 then the program will output "You are going to starve." After the final loop the program will display the lowest amount spent on any one week along with the most spent on any one week.
Lab Goal : This lab was designed to teach you how to use a while loop. Lab Description (JAVA PROGRAMMING): Remove all occurrences of the removal string from the original string. Each time you take out the removal string you must also remove the letter that preceded the removal string. After you remove a string and its leading character, you must check to see if any more occurrences of the removal string exist. Sample Data : xR-MxR-MHelloxR-M R-M sxsssxssxsxssexssxsesss xs fuxqwexqwertyxqwexqwe Sample Output : xR-MxR-MHelloxR-M - String to remove R-M Hello sxsssxssxsxssexssxsesss - String to remove xs sesss fuxqwexqwertyxqwexqwertyrtyxqwertyrtyn - String to remove qwerty fun dogdogcatddodogdogdoggog - String to remove dog catgog algorithm help use indexOf to look for more removals while you have more removals { take out the current removal using substring use indexOf to look for more removals } I need help with assignment: "String Cleaner" StringRemover.js: //(c) A+…

LAB ASSIGNMENTS, CONT. 2. sandwich.py - follow the instructions below. You may adjust the food items to include your personal favorites. • It uses all of our standard mipo_ex features. • The menu should have numbered or letter options. Sandwich Maker Write a program that asks users for their sandwich preferences. The program should use PylnputPlus to ensure that they enter valid input, such as: Using inputMenu() for a bread type: wheat, white, or sourdough. Using inputMenu() for a protein type: chicken, turkey, ham, or tofu. Using inputYesNo() to ask if they want cheese. If so, using inputMenu() to ask for a cheese type: cheddar, Swiss, or mozzarella. Using inputYesNo() to ask if they want mayo, mustard, lettuce, or tomato. Using inputlnt() to ask how many sandwiches they want. Make sure this number is 1 or 120 00T 110 more. Come up with prices for each of these options, and have your program display all the choices and their prices plus a total cost at the very end. 3 130
AdderAA.java This program will allow the user to select how many numbers they’d like to add together, and then enter those numbers to be totaled. The program should run in a continuous loop unless the user enters zero at the menu (in this case the program should end). A negative menu answer should give an “invalid response.” Your code should catch input mismatches. There will be multiple loops and probably an if/else structure required to accomplish this. You cannot use a break statement or any other non-logical way such as System.exit to exit a loop. This will result in a loss of major points. The example below is one continuous run of the program. Your program should run the test case exactly as it appears below, and should work on any other case in general. Output Example This program will add numbers together. Tell me how many numbers you’d like to add or type 0 to end the program. >>>3 Enter your number: 4.0 Enter your number: 3.2 Enter your number: -1.0 The sum of your…
