CS 165 01 Final Project

  

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 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];

Write a program that displays a menu with the following options:

1. The user can enter a number in an input box and the program will tell the user if the number is prime and, if so, if it is also an emirp.

2. The user can enter a number in an input box and the program will display in a listbox all the prime number and all the emirp numbers from 1 to that number.

3. The user can enter a filename that contains a list of numbers and the program will display all prime number and all emirp numbers in the file and display the results in the listbox.

4. Quit the program.
