Computer Science C# Programming Object Orientation Please use Arrays or ArrayLists where appropriate Implement a menu driven program that has some operations for a food truck. A food truck has multiple food items as well as a menu which contains a selection of the food items which will be sold for that day. A maximum of 10 food items can appear on the menu for any day. For each food item keep a code, description, category, price and quantity in stock (code, description and category are not usually changed). Create a comma delimited text file called "items.txt" for 15 or more food items, indicating the item's description, category, price and quantity in stock. Read all the food items from the text file “Items.txt” Display all the food items available for this food truck. Continuously prompt the user for a food item’s code to be placed on the menu until the menu is full or the user enters -1. Note that only food items which have a positive quantity in stock may be added to…

Using C# in Microsoft Visual Studio Create an application that simulates a game of tic-tac-toe. The application should use a two-dimensional int array to simulate the game board in memory. When the user clicks the New Game button, the application should step through the array, storing a random number in the range of 0 through 1 in each element.The number 0 represents the letter O, and the number 1 represents the letterX. The form should then be updated to display the game board. The application should display a message indicating whether player X won, player Y won, or the game was a tie.
MUST BE WRITTEN IN C PROGRAMMING LANGUAGE CANNOT EDIT TEMPLATE IMAGE IN ANY WAY: Write a program to find and display the largest value in an integer array that is divisible by 3. For example, if the array is: 1 15 2 16 3 17 4 18 5 19 The largest number divisible by 3 is 18 On the other hand, if the array does not contain any values that are divisible by 3, the program writesNo value in the array is divisible by 3As you may see in the examples, the input consists of, firstly the size of the array, followed by the array elements. The answer is preloaded with the code to read in the array. Do not change this code. The Moodle checker expects *exactly* the output as shown. For example: Input Result 6 1 2 3 4 5 6 The largest value divisible by 3 is 6 6 1 -2 4 5 -7 8 No value in the array is divisible by 3
(Electrical eng.) Write a program that specifies three one-dimensional arrays named current, resistance, and volts. Each array should be capable of holding 10 elements. Using a for loop, input values for the current and resistance arrays. The entries in the volts array should be the product of the corresponding values in the current and resistance arrays (sovolts[i]=current[i]resistance[i]). After all the data has been entered, display the following output, with the appropriate value under each column heading: CurrentResistance Volts
