- Code in C# (OOP Concept) Do a program that does the following: Ask for a number from the user in the main method o Pass thenumber to a method call it "Multiplication”. In the Method Multiplication, multiply the number by a number enteredby the user (mention that the number should be positive). Send the result back to the main and print it from the mainModify the previous program if the user enters a negative second number in the method Multiplication, do not acceptthe number and ask the user to reenter it again. . Add another method call it also Multiplication Ask for a float numberfrom the main and send it to the new Multiplication. This method should also ask for another positive number fromthe user and multiply it by the float number. Design and implement a function called "multiply" in C++ that accepttwo numbers and returns either the arithmetic multiplication or repetition of a given string a specific number of timesdepending on the data types of the argument values. The…3) Write a program called AveMethod (main method) that contains a method called threeAve (method name) that computes the average of three numbers. NO CREDIT if a method is not used. (7 pnts) a) The main method will do the following: asks the user for 3 number (double type). calls the threeAve method print the average of the three numbers b) The threeAve method will do the following: receives 3 numbers (parameters) calculate the average of the three numbers returns the average ● Sample Run: Input the first number: 2.5 Input the second number: 3.5 Input the third number: 6.6 The average is 4.2 Submission ● Copy and paste your code Screen shot the console with the same Sample Run as aboveC# n Chapter 6, you continued to modify the GreenvilleRevenue program. Now, modify the program so that the major functions appear in the following individual methods: GetContestantNumber - This method gets and returns a valid number of contestants and is called twice once for last year’s number of contestants and once for this year’s value DisplayRelationship - This method accepts the number of contestants this year and last year and displays one of the three messages that describes the relationship between the two contestant values GetContestantData - This method fills the array of competitors and their talent codes GetLists - This method continuously prompts for talent codes and displays contestants with the corresponding talent until a sentinel value is entered An example of the program is shown below: Enter number of contestants last year >> 2 Enter number of contestants this year >> 3 Last year's competition had 2 contestants, and this year's has 3 contestants…
- (f) Write a non-static method isMultiple that determines, for a pair of integers, whether the second integer is a multiple of the first. The method should take two integer arguments, return true if the second is a multiple of the first, and return false otherwise.c# Now, modify the program so that the major functions appear in the following individual methods: GetMonth - This method prompts for and returns the month GetNumMurals - This method prompts for and returns the number of murals scheduled and is called twice -- once for interior murals and once for exterior murals ComputeRevenue - This method accepts the number of interior and exterior murals scheduled, accepts the month they are scheduled, displays the interior and exterior prices, and then returns the total expected revenue DataEntry - This method fills an array with customer names and mural codes and is called twice -- once to fill the array of interior murals and once to fill the array of exterior murals GetSelectedMurals - This method continuously prompts for mural codes and displays jobs of the corresponding type until a sentinel value is entered using systeml using static System.Console; using System.Globalization; class MarshallsRevenue { staticvoidMain() { // Your code here…T/F 5) The following two methods will both compute the same thing when invoked with the same value of x. That is,method1(x) = = method2(x).public int method1(int x){if(x > 0) return method1(x – 1) + 1;else return 0;}public int method2(int x){if(x > 0) return 1 + method2(x – 1);else return 0;}
- a) Write a boolean method called sumDivisibleByFive that returns true if the sum of the digits of its integer parameter is divisible by 5 and false otherwise. For example, if the parameter passed to the method is 73 then the sum of its digits is 10 (7+3) The method should return true since 10 is divisible by 5. b) Write a main method that calls the method sumDivisibleByFive for the values between 10 and 100 inclusive 10 per line. This should output the following numbers: 14 19 23 28 32 3741 46 50 55 64 69 73 78 82 87 91 962. Case Problems 1 (three parts) - a - Carly’s Catering provides meals for parties and special events. In Chapter 2, you wrote an application that prompts the user for the number of guests attending an event, displays the company motto with a border, and then displays the price of the event and whether the event is a large one. Now modify the program so that the main() method contains only three executable statements that each call a method as follows: The first executable statement calls a public static int method that prompts the user for the number of guests and returns the value to the main() method. The second executable statement calls a public static void method that displays the company motto with the border. The last executable statement passes the number of guests to a public static void method that computes the price of the event, displays the price, and displays whether the event is a large event.
