Find power of a number using recursion in C#
To find the power of a number, firstly set the number and the power −
int n = 15; int p = 2;
Now create a method and pass these values −
static long power(int n, int p) { if (p != 0) { return (n * power(n, p - 1)); } return 1; }
Above, the recursive call gave us the results −
n * power(n, p - 1)
The following is the complete code to get the power of a number −
Example
using System; using System.IO; public class Demo { public static void Main(string[] args) { int n = 15; int p = 2; long res; res = power(n, p); Console.WriteLine(res); } static long power(int n, int p) { if (p != 0) { return (n * power(n, p - 1)); } return 1; } }
Output
225
