Given : An array with 25 elements

To Find : What is the index number of the last element of an array with

              25 elements ?

Explanation :

Array is a derived or secondary datatype, which contains elements of same datatype in contiguous memory location. Arrays are used in all programming languages like, C, C++, Java, Python, Javascript, etc. Array is also the most basic data structure, as it is used to store data, in a specified manner in continuous memory locations. In array, the index starts from 0, so the index of the last element is always one less than the length of the array.

As in the given question it states that the array has 25 elements. It means the length of the array is 25, and hence , index of the last element will be 24 (25 - 1 = 24).
