I have tried the two ways below to get my functions to call and run, but VS gives me the error

error c2660: ..... function does not take 0 arguments

First way tried

```
//Michelle CSI 130 Lab 11 Part 2 Section B
//Digital logic and Boolean algebra
#include <iostream>

int Lowest (int n, int low)

Any help is appreciated.
