Which loop (while, do-while, or for) is best to use in the following situations?
A) The user must enter a set of exactly 14 numbers.
B) A menu must be displayed for the user to make a selection.
C) A calculation must be made an unknown number of times (maybe even no times).
D) A series of numbers must be entered by the user, terminated by a sentinel value.
E) A series of values must be entered. The user specifies exactly how many.

- Case1: Write a menu driven program that allows you to visit cities of oman in random order with following options. 1: Visit a city 2: Go to previous city 3: Quit the program When user presses 1: program asks user to enter the city name, and then display that the city has been visited. Please note user can visit a city any number of times When user presses 2: Program takes you back to the previous city When user presses 3: Program terminates See the below example how program interacts with the user: C:> 1: Visit a city2: Go to previous city3: Quit the program Enter your choice … 1 Please enter a city to visit..

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…arrow_forwardEven 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.

- Direction: Perform what is asked below. CASE: Due to the present situation that we are facing, which is the pandemic, the government decided to limit the type of rice the consumer can purchase to one. With your help as a programmer, the government ask you to create such program. The program should be able to display the menu as displayed below. The user will be allowed to enter the choice, quantity in kilo grams (kg) and payment amount. The program should also be able to output the total amount due and the change. Organize your algorithm in such a way that it is logically correct, usable and functional.

Checkboxes are used in designing the user interface for situations where the user may choose only one of a few choices. Boolean variables are often used to improve the readability / clarity of the program code. For Next loops can have both negative and positive step values. If no item has been selected in a listbox, the SelectedIndex property of the listbox will have a value of zero. A Boolean variable must be initialized after the If instruction in which it is used is executed. A post-test loop is a loop that is designed to be executed at least once. In coding a Select Case instruction, the only thing that may appear after the Select Case keywords is a variable. A Do loop begins with the keyword Do and ends with the keyword Loop. The condition that controls a Do Until loop must be true for the loop to be executed.

Cut and paste your code from Eclipse into the Assignment text window. This is another password program. In this case, your code is simply going to ask for a username and password, and then check the input against four users. The program will give the user three tries to input the correct username-password combination. There will be four acceptable user-password combinations: alpha - alpha1 beta - beta1 gamma - gamma1 delta - delta1 If the user types in one of the correct username-password combinations, then the program will output: “Login successful.” Here are a couple of example runs (but your code needs to work for all four user-password combinations): Username: betaType your current password: beta1Login…arrow_forward
