Final answer:
To access the last two people in an array, index the array using the length property minus one for the last person, and length minus two for the second to last person, ensuring the language's indexing rules are followed.
Step-by-step explanation:
To access the last two people in an array named people, you would need to perform indexing on the array. Since the question is not specific to a programming language and it explicitly states it cannot be done in C, I will provide a general approach that can be adapted to many programming languages.
Most programming languages use zero-based indexing for arrays, meaning the first element is at index 0. To get the last element of the array, you would access the element at the index equal to the length of the array minus one. To get the second to last element, you would access the element at the index equal to the length of the array minus two.
If we're working in a language like Python, and the array people has at least two elements, the code would look like this:
last_person = people[-1]
second_to_last_person = people[-2]
In other languages, you may not be able to use negative indices directly, so you would typically use the length property of the array (like people.length in JavaScript) to calculate the positions:
var arrayLength = people.length;
var last_person = people[arrayLength - 1];
var second_to_last_person = people[arrayLength - 2];
Remember to verify the array has enough elements to avoid errors.
