In computer science, an array data structure, or simply an array, is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key.

Java ArrayList get first and last element example shows how to get the first and last elements of ArrayList in Java. The example also shows how to check the size of ArrayList before getting the elements to avoid IndexOutOfBoundException. How to get first and last element of ArrayList in Java? ArrayList is an index based data structure. I'm trying to create a function that will return the last element of an array. I am working in ANSI C.
