Question

Write a program to find x to the power n (i.E. X^n). Take x and n from the user. Y

Answer 1

import java.util.*;

class program

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.println("Enter x and n");

int x=sc.nextInt();

int n=sc.nextInt();

System.out.println("Here we gooooo : "+Math.pow(x,n));

}

}

Answer 2

Here is the C program's source code for computing the value of X N. The compilation of the C programme is successful.

/*

 C programme that takes X and N as inputs will calculate the value of X N.

*/

#include <stdio.h>

#include <math.h>

long int power(int x, int n);

void main()

{

   long int x, n, xpown;

   printf("Enter the values of X and N \n");

   scanf("%ld %ld", &x, &n);

   xpown = power(x, n);

   printf("X to the power N = %ld\n", xpown);

}

/*  Recursive function to computer the X to power N */

long int power(int x, int n)

{

   if (n == 1)

       return(x);

   else if (n % 2 == 0)

       /*  if n is even */

       return (pow(power(x, n/2), 2));

   else

       /*  if n is odd */

       return (x * power(x, n - 1));

}
