What are recursive method calls in C#?

Recursive method calls in C# are called recursion. Let's look at an example of calculating powers of numbers using recursion.

Here, if the power is not equal to 0, a function call occurs, which ends up being recursive -

if (p!=0) { return (n * power(n, p - 1)); }

Above, n is the number itself, and the power is reduced with each iteration, as shown below -

Example

using System; using System.IO; public class Demo { public static void Main(string[] args) { int n = 5; 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; } }
