How to sum of natural numbers using recursion?

Question

What are the difference between for loop and recursion

Answer 1

Mike
Recursion is a function which calls it self until an return statement is incountered. In C and C++ we use an if statement or the function will recurse infinitly. If you are a beginner with Recursion use a print to prevent any problems before it's too late.
Loops:
Faster than recursion.
Easy to use.
Used widely.
Recursion:
Slower than loops.
Uses more memory.
Hard to understand.
Recursion is the simplest algorithm in some programming situation but loops are better.

Happy Recursion!

Here's a link to the course section covering recursion. Loops are covered earlier, you'll get to it soon (if you haven't already)

Answer 4

To calculate the sum of natural numbers using recursion in C, we follow a simple approach where the problem is divided into smaller problems, and those smaller problems are solved individually. The base condition in this recursive function will be when the number n is 1, in which case the function should return 1. Otherwise, the function calls itself with n-1 and adds n to the result of that call. This process repeats until the base condition is met.

#include <stdio.h>

// Function declaration
int sumOfNaturalNumbers(int n);

int main() {
int n, sum;

printf("Enter a positive integer: ");
scanf("%d", &n);

sum = sumOfNaturalNumbers(n);

printf("Sum = %d", sum);
return 0;
}

// Function to find the sum of natural numbers using recursion
int sumOfNaturalNumbers(int n) {
if (n != 0)
return n + sumOfNaturalNumbers(n - 1); // Recursive call
else
return n;
}
