C# Programming Assignment

Section A:

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.

 

Section B:

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 section A that returns true if a number is prime; false otherwise and another method that returns the reversal of a positive number. Your program should have a TextBox that will accept a positive integer from the user and then display whether the positive integer is an emirp.
