C Program using Two argument passing function

C# Program using Two argument passing function

Program Statement:

Write a function which takes two values n1 and n2 as arguments and multiply the n1 by itself n2 times i.e. calculate n1n2 and then return the result to main function which will display the result.

Solution:

 class power_fun
 {
 double x;
 public 
 power_fun()
 {
 x = 1;
 }
 double power(int a,int b)
 {

 for (int i = 1; i <= b; i++)
 {
 x = x * a;
 }
 return x;
 }

 static void Main(string[] args)
 {
 power_fun p = new power_fun();
 int n1, n2;
 double result;
 Console.Write("Enter 1st Value: ");
 n1 = Convert.ToInt32(Console.ReadLine());
 Console.Write("Enter 2nd Value: ");
 n2 = Convert.ToInt32(Console.ReadLine());
 result= p.power(n1, n2);
 Console.WriteLine(n1+"^ "+ n2+" = "+ result);
 Console.ReadLine();
 }
 

C Program which calculated factorial to prime function

C# Program which calculated factorial to prime function

Program Statement:

Write two functions max(int,int) and prime(int). max function will take two arguments and will return the maximum of two numbers in main. Then main function will pass this calculated factorial to prime function which will show that passed value is prime or not.

Solution:

 public class _max
 {
 public int max(int a, int b)
 {
 if (a > b)
 return a;
 else
 return b;
 }
 public void prime(int n)
 {
 if (n == 1)
 Console.WriteLine(" {0} is maximum but not prime number! ", n);
 if (n >= 2)
 {
 if (n % 2 != 0)
 {
 Console.WriteLine(" {0} is maximum and Prime number! ", n);
 }
 else
 { Console.WriteLine(" {0} is maximum but not a Prime number! ", n); }
 }
 }
 }
