Write a program that reads in 5 marks. Your program must use the getMark method to ensure that valid marks are processed. You need to calculate the sum and the average of the marks. Your program must also use the isPass method to determine the number of pass marks entered. When the 5 marks have been processed you need to display the sum, average and number of passes (from these marks).

Write a user defined method named isPass that can be used to determine whether a mark is a pass mark (greater or equal to 50). The method must take as input a mark, and return a boolean, indicating whether the mark was a pass mark.

Create an application that calculates and prints the first n Tribonacci numbers. The Tribonacci sequence is a generalisation of the Fibonacci sequence which starts with three predetermined terms (0, 0, 1) and in which every term thereafter is the sum of the three preceding terms.. The Main method is provided. Copy it and leave it as is. Your task is to define the Tribonacci method. The screen print below shows the expected output for n = 10. Your method must use a counter-controlled while loop to calculate the terms. You are not allowed to make use of collections (arrays or lists). static void Main(string[] args) { int iFirst = 0, iSecond = 0, iThird = 1; Console.Write("Enter n (n >= 3) to display the first n Tribonacci numbers: "); int n = int.Parse(Console.ReadLine()); Console.WriteLine(); Console.WriteLine(Tribonacci(iFirst, iSecond, iThird, n)); Console.Write("\nPress any key to exit..."); Console.ReadKey(); }

Star Children’s Academy has opened a movie theater in its own capacity to host movie afternoon once a week for every class (including all sections e.g. Class 1 has three sections Class1-A, Class1-B, Class1-C divided because of large strength in one class, so here one class means 3 sections’ students will be watching a movie together one week and then next week another class and its sections) covering the topics such as patriotism, kindness, love, self-awareness, animal care and protection, etc.   As a Visual Programmer, you are required to design and develop a Windows Form Application that facilitates the class teachers to reserve tickets on behalf of students for the movie.
