Part 1: In your program, write a method that accepts a positive integer and returns true if the number is a prime number and false otherwise. Note that 2 is the only even prime number. An odd integer is prime if it not divisible by any odd integer less than or equal to the square root of the number. Part2: A prime number whose reversal is also a prime number is called emirp. For example, 11, 13, 79 and 359 are emirps. Write a program that outputs to a ListBox the first 100 emirps. Your program must contain the method from Part 1 that returns true if a number is prime; false otherwise and another method that returns the reversal of a positive number. You can reverse the integer in the following way: • Convert the integer into a string value = num.ToString(); • Use the following code to reverse the integer string newNum = “”; for (int l = value.Length; l > 0; l--) newNum = newNum + value[l-1]; Also, your program should have a TextBox that will accept a positive integer from the user and then display whether the positive integer if an emirp. When you complete the program, do the following. 1. Create a folder with the following name: FinalProject Extra Credit: 10 Points In addition to using a ListBox for the output of the 100 emirps, also write these values to an output file. Add this as a method. You should use the values from the ListBox as output to the file.
