#include <stdio.h>
int main(void)
{
float n, x, i;
printf("Enter the number you wish to find the square root of.\n");

Consider this naive stack implementation in Elixir:
defmodule Stack do
defstruct name: "", value: 0
def init() do
_s = []
end

s_new = [%Stack{name: name, value: value}, s]
{:ok,s_new}
end
def pop(s) do
[h|tail] = s

I've been trying to figure out a clean way of managing mappings between two objects. In the case of this example, it's two hashes. This spec should illustrate the problem at hand:

A couple of comments first
It would be better to let your divide method should return an int, not do the output to System.out itself. Do the output in main like this:
public static void main(String[] args) {
System.out.println(divide(-4,-10));
}
The variables N and D are short and don't f...
