C# (FormatExceptions) Create an app that inputs miles driven and gallons used, and calculates miles per gallon. The example should use exception handling to process the FormatExceptions that occur when converting the input strings to doubles. If invalid data is entered, display a message informing the user.

PARTICIPATION ACTIVITY Arrange the following lines to make a program that determines when the number of people in a restaurant equals or exceeds 10 occupants. The program continually gets the number of people entering or leaving the restaurant. Ex: 2 means two people entered, and -3 means three people left. After each input, the program outputs the number of people in the restaurant. Once the number of people in the restaurant equals or exceeds 10, the program exits. If an Input MismatchException exception occurs, the program should get and discard a single string from input. Ex: The input "2 abc 8" should result in 10 occupants. Not all lines are used in the solution.

Usernames An online company needs your help to implement a program that verifies the username chosen by a new user. Their rules is described below: Username MUST contain at least 6 characters; Username cannot start with a number; Username can only contain letters or numbers. If valid, the username may be resgistered if it doesn't already exist in the system. You should not use built-in functions to determine the character type such as isnumeric() or islower(). Use the strings given alphabet and numeric to determine if each character is valid. Use the list registered to help you determine if the username is already registered. Don't forget to execute the cell below to use these strings # run this cell to create these variablesalphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'numeric = "0123456789"registered = ["john87", "topmage", "light4ever", "username2"] Write a function nameValidation which receives a String argument name.

C++ PROGRAM EXCEPTION HANDLING Write a program with a function that accepts a string from user. The function prints “Valid String” only when the string contains at least one capital letter, one vowel, one integer and one ‘@’ character. An example of a valid string is @Developer123. If the user enters any operators like +,*,= then your program must throw a character exception. If the string contains any brackets like {[(}]), then your program must throw an integer exception. Write appropriate catch blocks of these exceptions.
def test_func(a,b,c): return (a+b)/c This function is normally designed to be used with three numbers: a, b, and c. However, a careless coder may call this function with an ill combination of arguments to cause certain exceptions. Specifically, if any of a, b or c is not a valid number, then this code will produce a TypeError; and if a and b are valid numbers, and c is 0, then the code will produce a ZeroDivisionError. Your job is to enhance this function by adding proper try...except... blocks, surrounding and capturing the exceptions. When a TypeError occurs, instead of crashing, your code must print on the screen: "Code produced TypeError". And, when a ZeroDivisionError occurs, instead of crashing, your code must print on the screen: "Code produced ZeroDivisionError". In both cases, your function will not crash, will not throw an exception, and silently return None.
