You would write code in your record_preferences just as you did here. The logic of your loop and your statements will need to change, though; you cannot force the logic you are using into the confines of how the problem specifications want you to solve it. For example, I was able to solve this with a nested for loop structure with a single line of code. I'm sorry, but I don't know what else to help you with. You are using arrays correctly in your main and unless you show me how you are writing the record_preferences function, I cannot tell you why it isn't working.

It does pass an entire array, but you don't need to understand pointers. You just need to understand arrays. You also don't need to pass an index to the function, as this should be taken care of inside of the function itself--you should not be changing the function declarations. If you want to edit your question to add your code for your record_preferences function, I can try to help you more, but I assure you that you can complete this without any knowledge of pointers. Your code inside the function will index into the array just as if you were writing code in the main function.

No, it doesn't. I never once mentioned pointers; nothing about what we are discussing here is talking about pointers. You will use an index to get values from the ranks array in the record_preferences function just as was needed to add the values in the vote function. Your questions where "what does ranks[] mean?" and "how am I supposed to code record_preferences(ranks[])?", which my answer has answered. :) This is doable without the use of pointers and you have all of the knowledge you need. Don't overthink it and treat it like any other array.
