However, I get past my scanf function that has the user choose the iteration size, even including a 2nd print function to test where the program stops (it prints 11 – the # of elements in my array), but that is where it stops, it doesn’t go through my returnNth function, even though every parameter is given…. Any help is greatly appreciated! sorry if this is a simple fix….
