C# Sharp Exercises: Print the natural numbers from n to 1
C# Sharp Recursion: Exercise-2 with Solution
Write a program in C# Sharp to print numbers from n to 1 using recursion.
Pictorial Presentation:
Sample Solution:
C# Sharp Code:
using System;
class RecExercise1
{
static int printNatural(int ctr,int stval)
{
if (ctr < 1)
{
return stval;
}
Console.Write(" {0} ",ctr);
ctr--;
return printNatural(ctr,stval);
}
static void Main()
{
Console.Write("\n\n Recursion : Print the natural numbers from n to 1 :\n");
Console.Write("--------------------------------------------------------\n");
Console.Write(" How many numbers to print : ");
int ctr= Convert.ToInt32(Console.ReadLine());
// Call recursive method with two parameters.
printNatural(ctr,1);
Console.Write("\n\n");
}
}
Sample Output:
Recursion : Print the natural numbers from n to 1 : -------------------------------------------------------- How many numbers to print : 20 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
