C Program to Find Sum of Natural Numbers using Recursion

WebJan 28, 2014 · The sum of the digits of n is ∑ k = 0 N a k. If a 0 + a 1 ≤ 9, the sum of digits of n ′ is ∑ k = 1 N a k + a 0, which is the same as the sum of the digits of n. If a 0 + a 1 ≥ 10, then the last digit of n ′ is a 0 ′ = a 0 + a 1 − 10 and the second to last digit is a 1 ′ = a 2 + 1 if a 2 ≤ 8 a 1 ′ = 0 if a 2 = 9. WebI am trying to write a function using only recursion (and no built-in functions) that consumes two numbers, x and y and produces the sum. 1 + x + x^2 + ... + x^(y-1) + x^y. Note that I am looking for a way to do this without using for/while loops because I have not learned them yet. So far, I have the following function: longmont co backflow
