Write a function that prints even numbers in a range of integers using recursion.


Difficulty level
This exercise is mostly suitable for students
#include<stdio.h>
#include<conio.h>

void printEvenNaturalNumbers(int lowerLimit, int upperLimit)
{
    	if(lowerLimit <= upperLimit)
    	{
		if(lowerLimit%2)
            		printEvenNaturalNumbers(lowerLimit + 1, upperLimit);
            	else
                {
                  	printf("%d ", lowerLimit);
    			printEvenNaturalNumbers(lowerLimit + 2, upperLimit);
                }
	}           
}

void main()
{
 	int lowerLimit, upperLimit;
	 
    	printf("Enter the lower limit: ");
    	scanf("%d", &lowerLimit);
    	printf("Enter the upper limit: ");
    	scanf("%d", &upperLimit);

    	printf("Even Natural numbers from %d to %d are the following: ", lowerLimit, upperLimit);
    	printEvenNaturalNumbers(lowerLimit, upperLimit);
 
	getch();
}
