C# program to print Factorial of all Prime numbers

Program Statement:

Write a program using loop which takes one value n from user and show the factorial of all prime numbers which are less then n. e.g. if n = 10 then program will print the factorial of 2,3,5,7.

Solution:

 public class fop
 {
 int x, a, b, p, fac=1;
 public void fact()
 {
 Console.WriteLine(" Show factorial of primes less than n ");
 Console.Write(" Enter ending point : ");
 x = Convert.ToInt32(Console.ReadLine());
 for (a = 2; a < x; a++)
 {
 p = 1;
 for (b = 2; b < a; b++)
 {
 if (a % b == 0)
 { p = 0; }
 }
 if (p == 1)
 {
 fac = 1;
 for (int c = 1; c <= a; c++)
 { fac = fac * c;}
 Console.Write(" Factorial of {0} is : {1} ", a,fac);
 }
 }
 Console.WriteLine(" ");
 }
 }
